Answer:
72 units
Step-by-step explanation:
A circle has a circumference of 452.16
The formula for circumference of circle = [tex]2\pi r[/tex]
Where r is the radius of circle
The approximate value of pi = 3.14
Given circumference C= 452.16
[tex]C = 2\pi r[/tex]
[tex]452.16 = 2(3.14)r[/tex]
[tex]452.16 = (6.28)r[/tex]
Divide both sides by 6.28
r = 72
So radius of the circle 72 units
