The zoo is building a new polar bear exhibit and wants to put a semi-circular window in the concrete wall of the swimming tank. If the semi-circle has a diameter of 10 m and the bottom of the window is at a depth of 23 m, find the hydrostatic force on the window. Water density is 1000 kg/m^3 and acceleration due to gravity is 9.8 m/s^2. If necessary, round your answer to the nearest Newton.
