The volume of this sphere is 972pi cubic inches. What is its radius?

4/3pi * r3 = 972pi

Divide both side by pi

4/3 * r3 = 972

r3 = 972 * 3/4

r3 = 729

r = the square root of 729 to the third power (I don't know if I'm expressing this correctly but answer is 9, hope you get that)

r = 9 that's your answer.

Hope it's correct, appreciate if you could let me know
