The formula for volume of a sphere is:
V = 4/3 * PI * r^3
Replace r with with given radius:
V = 4/3 * pi * 17^3
V = 4/3 * PI * 4913
You don't give the choices, but anything like the two equations I gave could be correct. Might even multiply the 4/3 by r^3?
If you list the choices I can tell you which one.
