Water is draining from a conical tank with height 12 feet and diameter 8 feet into cylindrical tank that has a base with area 400pi square feet. The depth h, in feet, of the water in the conical tank is changing at the rate of (h-12) feet per minute. (The volume V of a cone with radius r and height h is V = 1/3pir^2*h). a) Write an expression for the volume of water in the conical tank as a function of h. b) At what rate is the volume of water in the conical tank changing when h = 3? Indicate units of measure for a) i got $\frac{ \pi }{ 27 } h ^{3}$ and b) i got 9pi ft/min
