(2) Water is leaking from a paper cup, at a rate of 25cm3/min. The cup is shaped like a cone. The cone has height 10cm, and the diameter at the top is 4cm. At what rate is the water level dropping when the water is 1cm deep? (Hint: The volume of a cone is V = ??h.)

at the same time that water is being pumped into the tank at a constant rate. The tank has height 6 m and the diameter at the top is 4 m. If the water level is rising at a rate of 20 cm/min when the height of the water is 2 m, find the rate at which water is being pumped into the tank.
