Can someone find the diameter of a sphere with a volume of 972Π?

 

P.S.: Π = pi (a.k.a. 3.141592653589...)

972 pi  = (4/3) * pi * (r^3)     divide both sides by pi

972  = (4/3) * r^3      multiply both sides by 3/4

729 = r^3      take the cube root of both sides

9 = r    and the diameter is twice this  = 18
