Question

Classic work done on water pumped from an inverted right cone. Top of the cone is r=4ft, h=10ft. What is the work done getting the water out, assuming it's full to the top, and what is the work to get it out if you raise it 10 ft higher? I've tried a couple times, but keep getting the wrong answer. (See the attached image.)
