Answer:
Rate of change of volume of the pile 
Explanation:
Given -
Rate of increase of the base of the pile
inches per minute
Height of the pile
the radius of the base
Let "h" be the height of the pile and "r" be the radius of the base.
Then 
Radius "r"
inches
Rate of change of radius i.e

Volume of conical pile

Change in volume of conical pile

Substituting the value of rate of change of radius, we get -

Rate of change of volume of the pile
