A snowball is rolling down a hill and the radius of the snowball is increasing at a constant rate of $~0.2~\dfrac{\text{cm}}{\text{sec}}\,$. (The volume of a sphere is $\dfrac{4}{3}\pi r^3$) **What is the rate of change of the volume of the snowball when the volume is $~36\pi ~\text{cm}^3\,$?** [[☃ radio 1]]
