Can someone please explain it to me ASAP??!!! A cylindrical tank, shown to the right, has height 5 m and radius 4 m. a. If the tank is full of water, how much work is required to pump the water to the level of the top of the tank and out of the tank? Use 1000 kg / m for the density of water and 9.8 m/s for the acceleration due to gravity. b. Is it true that it takes half as much work to pump the water out of the tank when it is half full as when it is full? Explain. .... a. Draw a y-axis in the vertical direction (parallel to gravity) and choose the center of the bottom of

A cylindrical tank, shown to the right, has height 5 m and radius 4 m. a. If the tank is full of water, how much work is required to pump the water to the level of the top of the tank and out of the tank? Use 1000 kg / m for the density of water and 9.8 m/s' for the acceleration due to gravity. 5 m b. Is it true that it takes half as much work to pump the water out of the tank when it is half full as when it is full? Explain. 4 m a. Draw a y-axis in the vertical direction (parallel to gravity) and choose the center of the bottom of the tank as the origin. For 0sys 5, find the cross-sectional area A(y). A(y) =(Type an exact answer, using x as needed.) Set up the integral that gives the work required to pump the water out of the tank. Use increasing limits of integration.
