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
