#5) The conical tank in problem #4 is full of a liquid which has a density of . How much work is done lifting the water to a distance 2h above the top of the cone? (similar to 5.3 #12) Hint: Put the origin of your x-y coordinates at the vertex of the cone. With this coordinate system, the water lies between y = 0 and y = h. The water is pumped to a height of y = 3h. Express your answer in terms of ρg, h, r, and π.
