' Question 1 "' 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. [Note: picture is not to scale] If the semicircle has diameter 6i] centimeters, and the bottom of the window is at a depth of 2.?5 meters, find the hydrostatic force on the window. mm ' Question Er 1" The Deligne Dam on the Eagle; River is built so that the 1wall facing the water is shaped like the region above the curve 3; = 114132 and belowr the line y = 28D. {Here, distances are measured in meters] The water level is 38 meters below the top of the dam. Find the force {in Newtons] exerted on the dam by 111 water pressure. {Water has a density of lE, and the acceleration of gra'oi'ityur is 9.32 .}| m EEC
