An underground tank full of water has the shape of a circular cone with a base radius 5m and height 4m at the top. The top of the tankl is 2m below the ground-surface and is connected to the surface by a spout. Find the work required to empty the tank by pumping all of the water out to the surface. Density= 1000kg/m^3 and gravity= 10 m/s^2)
