Recall, the volume of a sphere is V=4/3πr^3. If the sphere is increasing in size over time, then we may treat volume and radius as functions of time. That is, V(t)=4/3π[r(t)]^3 Suppose the radius of the sphere is increasing at a constant rate of 1.5 centimeters per second. At the moment when the radius is 21 centimeters, the volume is increasing at a rate of__cubic centimeters per second.
