D.79.6
Step-by-step explanation: The formula to find the volume of a sphere is V=4/3*pi*r^3.
The volume of the sphere with the radius of 2 is 33.5
The volume of the sphere with the radius of 3 is 113.04
Subtract 33.5 from 113.04 and you get 79.59.Now round up to the nearest tenth and you get 79.6 cm
