4. Sand is falling off a conveyor and into a conical pile. The Volume V of the pile is given by V = - where r is the radius of the base in feet. The 3 circumference of the base is increasing at a constant rate of 57 feet per hour. When the circumference of the base is 87 feet, what is the rate of change of the volume of the pile, in cubic feet per hour?
