The volume of a sphere with radius
r is
(4)/(3)\pi r^3. If the radius is multiplied by a constant
k, then the new volume is
(4)/(3) \pi (kr)^3, which is equal to
k^3 \cdot (4)/(3) \pi r^3. This means that the volume of the sphere is multiplied by
k^3.

a. If the radius is doubled, the volume is multiplied by 8

b. If the radius is tripled, the volume is multiplied by 27

c. if the radius is quadrupled, the volume is multiplied by 64
