A tank has the shape of an inverted circular cone with height 10 m and base radius 4 m. It is filled with water to a height 5 m. Set up an integral to find the work required to empty the tank by pumping all of the water through a pipe that rises to a height of 2 m above the top of the tank. (The density of water is 1000kg per m3.) (Set up only. Do not evaluate the integral!)
