To find the radius of a sphere when you have the circumference, divide the circumference by 2pi.

Explanation:

7.4pi divided by 2pi would be 36.51753628 <—— and round that number up

Please note that I might be wrong as I have not learned this in have learned it in class but just don’t remember it.

7.4 pi =2 pi r

divide both side by pi

7.4/2=r

3.7 = radius
