The radius of a right circular cone is increasing at a rate of 5 inches per second and its height is decreasing at a rate of 3 inches per second. At what rate is the volume of the cone changing when the radius is 20 inches and the height is 30 inches? (in cubic inches per second) NOTE: The volume of a cone with base radius rr and height hh is given by V=1/3pi r2h
