A reservoir is shaped like a straight circular cone, with the top pointing down (like an ice cream cone). Its height is 7 m, the radius of its circular upper face is 4 m, and it is filled with water to a height of 5 m. The purpose of this question is to determine the total work required to pump the entire amount of water to a height of 1 m above the top of the reservoir. Reminder: the density of water is = 1000 kg/m3 and the acceleration due to gravity at the surface of the earth is g = 9.8 m/s2
