The tank in the form of a right-circular cone of radius 11 feet and height 38 feet standing on its end, vertex down, is leaking through a circular hole of radius 4 inches. Assume the friction coefficient to be c = 0.6 and g = 32 ft/s2. Then the equation governing the height h of the leaking water is dh dt = If the tank is initially full, it will take it seconds to empty.
