INTEGRAL CALCULUS:
A cylindrical gasoline tank is placed so that the axis of the cylinder is horizontal. Find the fluid force on a circular end of the tank if the tank is half full, assuming that the diameter is 3 feet and the gasoline weighs 42 pounds per cubic foot. please explain how you come up with the answer in detail if you can.

SO. start by graphing the circle on the x-y plane. You know the area of the circular endcaps. You can integrate (top minus bottom) or just use pi*r^2. Then you can get to integrating the force due to the gas pushing out over the area of the bottom half. all of the integrals depend on where you graph your circle.
