Aconical tank is leaking water at the rate of 75 cubic inc/min. at the same time water is being pumped into the tank at a constant rate. the tanks height is 60 in whiles its top diameter is 20 inches. if the water level is rising at a rate of 5in/min when the height of the water is 10 inches high, find the rate in which water is being pumped into the tank to the nearest cubic inhes/min. the volume of a cone is given by( v= 1/3pi*r^2*h)
