(1 point) a gas station stores its gasoline in a tank under the ground. the tank is a cylinder lying horizontally on its side. (in other words, the tank is not standing vertically on one of its flat ends.) if the radius of the cylinder is 1 meter, its length is 4 meters, and its top is 4 meters under the ground, find the total amount of work needed to pump the gasoline out of the tank. (the density of gasoline is 673 kilograms per cubic meter; use =9.8 m/s2.)
