----------
By the way, if the volume is  cm^3,
then the solution and the answer by @ewatrrr  are both I N C O R R E C T.
The correct solution is below
 =
Canceling pi in both sides
 = 972
 =  = 729
r =  = 9.
Surface area =  =  =  = . ANSWER.
The correct answer is .
Solved.

Hi,
 .
A sphere has a volume of 972π cm^3
|Can just use the word pi for posting. Note use of ^
What is its surface area?
Volume = 4/3 πr^3
r^3 = = 729
r = 27cm
Surface Area = 4πr^2 = 4π(27^2 ) = 2916π cm^2
Wish You the Best in your Studies.
