a water tank in the shape of a circular cone with its top down, with a base radius of 5cm and height of 10cm. pour water into it at rate of 9 pi cm 3/min. calculate the rate of change of height of water two minutes after the start of pouring water.

The volume of the water tank is (1/3)πr2h = (1/3)π(5)2(10) = 250π cm3.

The rate of change of height of water two minutes after the start of pouring water is (18π cm3)/(2 min) = 9π cm3/min.
