A tank containing oil is in the shape of a downward-pointing cone with its vertical axis perpendicular to ground level (See a picture of the tank ). Assume that the height of the tank is ℎ=8 feet, the circular top of the tank has radius r=4 feet, and that the oil inside the tank weighs 30 pounds per cubic foot.
