An inverted conical tank (meaning the flat part of the cone is upwards and the point is downwards) is 7 meters tall with a radius of 3 meters. The tank is filled to the 3 meter height with water. Set up, BUT DO NOT EVALUATE, an integral that calculates the amount of work needed to pump the water out of the tank through a pipe just above the top of the tank. Use the variables for the density of water and g for the acceleration due to gravity. This means your integral should have and g in it.
