An outdoor decorative pond in the shape of a hemispherical tank is to be filled with water pumped into the tank through an inlet in its bottom. Suppose that the radius of the tank is R = 10 ft, that water is pumped in at a rate of a ft/min, and that the tank is initially empty. As the tank fills, it loses water through evaporation. Assume that the rate of evaporation is
proportional to the area A of the surface of the water and that the constant of proportionality is k = 0.01.
Output: water evaporates
at rate proportional
to area A of surface

Input: water pumped in
at rate 7 ft/min

(a) The rate of change of the volume of the water at time t is a net rate. Use this net rate to determine a differential equation for the height h of the water at time t. The volume of the water shown in the figure is V = TRH2 - nh, where R = 10. Express the area of the surface of the water A = in terms of h.
