Find the diameter of a circle with an area of 804.25 cm
Answer:
The diameter of a circle with an area of 804.25 cm is 32 cm
Step-by-step explanation:
We know that formula for area of circle is:
Area of Circle = πr^2
804.25 = 3.14 * r^2
=> r^2 = 804.25 / 3.14
r^2 = 256.13
Taking square root on both sides
√r^2 = √256.13
r = 16.0
and r is half of diameter i.e
r = diameter / 2
=> diameter = 2r
so, diameter = 2 * 16
diameter = 32 cm
So, the diameter of a circle with an area of 804.25 cm is 32 cm.
The diameter is approximately [tex]\(32.02\)[/tex] cm, calculated from [tex]\(d = 2 \times 16.01\)[/tex], where [tex]\(r \approx 16.01\)[/tex] cm.
To find the diameter of a circle with an area of 804.25 cm², follow these steps:
Step 1:
Recall the formula for the area [tex](\(A\))[/tex] of a circle: [tex]\(A = \pi r^2\)[/tex], where r is the radius of the circle.
Step 2:
We're given the area [tex]\(A = 804.25\)[/tex] cm². Rearrange the formula to solve for [tex]\(r\)[/tex]: [tex]\(r = \sqrt{\frac{A}{\pi}}\)[/tex].
Step 3:
Substitute the given area into the equation: [tex]\(r = \sqrt{\frac{804.25}{\pi}}\).[/tex]
Step 4:
Calculate the radius: [tex]\(r[/tex] ≈ [tex]\sqrt{\frac{804.25}{\pi}}[/tex] ≈ [tex]\sqrt{256.25}[/tex] ≈ 16.01 cm.
Step 5:
Recall that the diameter [tex](\(d\))[/tex] of a circle is twice the radius: [tex]\(d = 2r\)[/tex].
Step 6:
Substitute the calculated radius into the equation: [tex]\(d = 2 \times 16.01\)[/tex].
Step 7:
Calculate the diameter: [tex]\(d[/tex] ≈ [tex]2 \times 16.01[/tex] ≈ [tex]32.02\)[/tex] cm.
Therefore, the diameter of the circle with an area of 804.25 cm² is approximately 32.02 cm.
The equation of a circle is (x+7)²+(y−13)²=196 .

) A number is chosen at random from 1 to 25. Find the probability of selecting
a prime number.
Answer:
Prime: 9/25 Not Prime: 16/25
Step-by-step explanation:
In 1 - 25 there are 9 prime numbers, or numbers that cannot be divided by anything other than 1 or itself. They are 2 3 5 7 11 13 17 19 and 23,
Selecting a NON Prime: 25-9= 16 so we would put 16 over 25.
16/25 since it can not be reduced that is the fraction
Selecting a Prime: We know there is 9 prime numbers so we would put it over 25. 9/25 also cannot be reduced any further,
Find the measure of a central angle of a regular polygon with 10 sides
Answer:
114 degrees
Step-by-step explanation:
The formula to find the measure of all angles in a regular polygon is [tex](n-2)180[/tex], where n = total number of sides.
Thus, we substitute n for 10, and you get:
[tex](10-2)180=1440[/tex]
If the shape is a regular polygon and it has ten sides, meaning all sides are equal, then all you do is divide 1440 by 10, to get the final answer of 114.
A central angle in a regular ten-sided polygon would be 144 degrees.
Final answer:
The central angle of a regular polygon with 10 sides (a decagon) is calculated by dividing 360° by the number of sides, resulting in a central angle of 36°.
Explanation:
To find the measure of a central angle of a regular polygon with 10 sides (a decagon), we use the formula for the measure of each central angle:
Central Angle = 360° / Number of sides
Thus, the central angle of a regular decagon is:
360° / 10 = 36°
This is because the central angles are equally distributed around the center point, dividing the 360° of a circle evenly by the number of sides in the polygon.

Answer:
x=-5/3
Step-by-step explanation:
ABD + DBC = ABC
Substitute the values
6x+9 + x+1 = 10x+15
Combine like terms
7x+10 = 10x+15
Subtract 7x from each side
7x-7x+10 = 10x-7x+15
10 = 3x+15
Subtract 15 from each side
10-15 = 3x+15-15
-5 =3x
Divide each side by 3
-5/3 =x
This will give us a negative value for DBC
DBC = -5/3 +3/3 = -2/3

A bicyclist covered 5/7 of his route and an additional 40 miles. He has yet to cover 118 miles less than 0.75 of his route. How long is his route in miles?
Answer:
168 miles.
Step-by-step explanation:
5/7x+40+0.75x−118=x
Step 1: Simplify both sides of the equation.
5/7x+40+0.75x−118=x
5/7x+40+0.75x+−118=x
(5/7x+0.75x)+(40+−118)=x(Combine Like Terms)
1.464286x+−78=x
1.464286x−78=x
Step 2: Subtract x from both sides.
1.464286x−78−x=x−x
0.464286x−78=0
Step 3: Add 78 to both sides.
0.464286x−78+78=0+78
0.464286x=78
Step 4: Divide both sides by 0.464286.
0.464286x/0.464286=78/0.464286
x=168
The total length of the bicyclist's route is 560 miles. This is solved by setting up an equation based on the given information and solving for the total route length.
Explanation:To solve this problem, we first need to represent the problem using equations by setting X as the total route. We know that the bicyclist has already covered 5/7 of his route and an additional 40 miles. So, the part of his route he has already covered is expressed as [tex](5/7)X + 40.[/tex]
We also know that he has yet to cover 118 miles less than 0.75 of his route, so the part of the route that he has yet to cover is expressed as 0.75X - 118. Since the parts of the route already covered and yet to be covered add up to be his entire route (X), we can set up the equation as follows: ([tex](5/7)X + 40 = 0.75X - 118[/tex]. By solving this equation, we find that X (the total length of his route) equals 560 miles.

Six is subtracted from a number the result is divided by four this result is added to 10 to give 30 what is the number
Answer: The number is 86.
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
"Six subtracted from a number ", a number means the variable (x), and six subtracted from a number is "x -6".
"The result is divided by 4", so (x-6) /4.
This result is added to then, so: 10+ (x-6) /4.
And finally, to give 30 means that all the expression equals to 30.
10+ (x-6) /4 = 30
Solving:
(X-6) /4 = 30 -10
(X-6) /4 = 20
X-6 = 20x4
X-6 = 80
x =80+6
x= 86
The number is 86.
The product of two whole numbers is 180 and their sum is36. What are the two numbers?
Answer:
6,30
Step-by-step explanation:
The product of two whole numbers is 180
xy = 180
and their sum is 36
x+y = 36
x = 36-y
Substitute this into the first equation
(36-y) (y) = 180
36y - y^2 = 180
Add y^2 to each side
36y = 180 +y^2
Subtract 36y from each side
0 = y^2 -36y +180
Factor
0=(y-6) (y-30)
Using the zero product property
y-6 =0 y-30 =0
y = 6 y= 30
Now we need to find x
If y =6
x = 36-6=30
If y = 30
x = 36-30=6
The two numbers are 30 and 6

2. What is the value of Z in the triangle? Round only you’re final answer to the nearest hundredth.
3. What is the value of X in the triangle? Round only you’re final answer to the nearest hundredth.
Answer:
1. X = 23.8 cm
2. Z = 12.5 Inches
3. x = 14.03 Degrees
Step-by-step explanation:
1. Given
Hypotenuse=25 cm
Angle=18 Degrees
We will use the trigonometric ratios for right angled triangles for finding the value of X.
In the given triangle, as X is the base, we will use the ration which involves base and hypotenuse.
So,
cosθ= Base/Hypotenuse
cos18=X/25
0.9510=X/25
0.9510*25=X
X=23.775
X=23.8 cm
2.The ratio of cos will be used for this one too.
Here,
Base=10 inches
Angle=37 Degrees
cosθ= Base/Hypotenuse
cos37=10/Z
0.7986=10/Z
Z=10/0.7986
Z=12.521
Z=12.5 inches
3. As we know the values of perpendicular and base ,
So the ration which involves these both will be used.
The desired ratio is
tan x=Perpendicular/Base
tan x=5/20
tan x=0.25
x = tan^(-1)0.25
x = 14.03 Degrees ..
The value of X and Z in a triangle should be determined by performing mathematical operations and rounding according to the specific rules of significant figures for addition, subtraction, multiplication, and division, following proper rounding at the final calculation to ensure precision.
Explanation:To answer the question regarding the value of X and Z in a triangle, it's important to note that the rounding of numbers should be done according to certain rules based on the operations involved.
In addition and subtraction, the result should have the same number of decimal places as the measurement with the least number of decimal places. For instance, adding 135.621, 97.33, and 21.2163 we get 254.1673, which is then rounded to 254.17 since the hundredth's place is the last common decimal place.
With multiplication and division, the answer should have the same number of significant figures as the original measurement with the least significant figures. Thus, multiplying 1.35 by 2.1 we get 2.835 and round it off to 2.8.
When dealing with whole numbers or in a series of steps, pay close attention to significant figures and round off only after the final calculation to prevent inaccuracies.
As an example, the complex calculation (13.2 + 12.252) x (1.35 x 2.1) should be rounded only once, after the entire expression is evaluated, leading to a result of 72.
