Problem 7: This problem will be graded for correctness. A spherical tank of radius 7 m is filled to a height of 10 m with water ($\rho = 1000kg/m^3$). Calculate the work required to move the water to the top of the tank. To earn full credit for this problem, you must: • Draw the tank and label it with the relevant information in the statement of the problem. • Draw a region in the $xy$-plane and indicate an axis so that the region produces the tank when revolved about the axis. • Write down equations that model the boundary curves of the region. These equations, along with any other quantities needed to set up the integral must be consistent with your coordinate system.
