Question

A circle has a circumference of 452.16452.16 units. What is the radius of the circle?

Answer 1

Answer:

72 units

Step-by-step explanation:

A circle has a circumference of 452.16

The formula for circumference of circle = $2\pi r$

Where r is the radius of circle

The approximate value of pi = 3.14

Given circumference C= 452.16

$C = 2\pi r$

$452.16 = 2(3.14)r$

$452.16 = (6.28)r$

Divide both sides by 6.28

r = 72

So radius of the circle 72 units
