A tank has the shape of a cylinder with height 15 m and base radius 4 m. There is a water spout on top of the tank with height 1 m. Suppose the tank contains water of height 10 m. Find the integral for the work required to pump the water out of the spout. Do NOT compute the integral. Suppose the water density is p=1,000 kg/m, and you may use the approximation g = 10 m/s for gravity. (Requirements: You need to set up the integral by using limit of Riemann sum. You will receive miminum points if you only provide the final integral without adequate justification.)
