Problem

Water is being pumped into a vertical cylindrical tank of radius 3 m at a rate of 4.0 m³/min. Simultaneously, water leaks out through a hole in the bottom at a rate of 0.10 m³/min for each meter of water depth. When the water depth is 5 m, calculate the instantaneous rate of change of the water depth, in m/min.
