How do i find the radius of s circle with the circumference of 272.2 inches? can anyone help

Certainly! To find the radius of a circle when you know its circumference, you can use the formula:

Circumference = 2 * π * radius

In this case, the given circumference is 272.2 inches.

First, divide both sides of the formula by 2π to isolate the radius:

radius = Circumference / (2 * π)

Now, substitute the given circumference value:

radius = 272.2 / (2 * π)

To calculate the value, you need to know the approximate value of π. Taking π as 3.14 (rounded to two decimal places) for simplicity:

radius ≈ 272.2 / (2 * 3.14)

Now, let's calculate the approximate value of the radius:

radius ≈ 272.2 / 6.28 ≈ 43.38 inches

Therefore, the approximate radius of the circle with a circumference of 272.2 inches is approximately 43.38 inches.

C = pi * 2r

272.2 = 3.14 * 2r

272.2 = 6.28r

272.2/6.28 = r
