CALCULATOR POLICY:
A tank is in the form of a right circular cone with the point down. The base of the cone is d = 6m in diameter, and the height of the cone is h = 3m. The tank is filled with water (density 1000kg/m3). Calculate the work it takes to empty this tank by pumping the water out over the top. A kilogram at the surface of the Earth weighs 9.81 newtons .
