Answer:

72 units

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
