find the radius and diameter of a circle with a circumference of 63m

To find the radius and diameter of a circle with a given circumference, you can use the formulas:

Circumference (C) = 2πr,
Diameter (D) = 2r,

where r represents the radius of the circle and π is a mathematical constant approximately equal to 3.14159.

Given that the circumference is 63 m, we can set up the equation:

63 = 2πr

To solve for r, divide both sides of the equation by 2π:

r = 63 / (2π)

Now we can calculate the approximate value of r:

r = 63 / (2 * 3.14159)
r ≈ 10.02 m

Therefore, the approximate radius of the circle is 10.02 m.

Next, we can find the diameter using the formula D = 2r:

D = 2 * 10.02
D ≈ 20.04 m

So, the approximate diameter of the circle is 20.04 m.

To find the radius and diameter of a circle, we need to use the formula for the circumference of a circle.

The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.

In this case, we are given the circumference (C) as 63m. So we can rearrange the formula to solve for the radius (r):

C = 2πr

63 = 2πr

To find the radius, we need to rearrange the equation to solve for r. Divide both sides of the equation by 2π:

r = C / (2π)

r = 63 / (2π)

Now let's calculate the value of r:

r ≈ 63 / (2 * 3.14)

r ≈ 63 / 6.28

r ≈ 10.05

Therefore, the approximate radius of the circle is 10.05 meters.

To find the diameter (d), we can use the formula d = 2r:

d = 2 * 10.05

d ≈ 20.1

Therefore, the approximate diameter of the circle is 20.1 meters.

C = pi * d

63 = 3.14d
63/3.14 = d
20.06 = d

d = 2r
20.06 = 2r
? = r
