Consider a conical-shaped tank with a small hole in the bottom through which liquid exits. In an instant, it was measured that the depth is 8 meters and the rate of change of depth is 0.3 m/s. At that same instant, the radius of the circle formed by the liquid surface is 6 meters and the rate of change of the radius is 0.3 m/s. What is the rate, in cubic meters per second, at which liquid is leaving the tank? Formula for the volume of a cone of height h and radius r:1/3 x πr^2h.
