A propane tank is made up of a cylinder with hemispheres on each end. If the total length of the tank is 6 feet and height is 2 feet, what is the volume of the tank? Round answer to nearest cubic foot?

If you put the two ends together, you have a sphere with a radius of 1 foot. Then you have a cylinder with a length of 4 feet and a radius of 1 foot. Compute both volumes and add them together.

4/3 pi r^3 + 4 pi r^2 and r is 1 so you can drop it.
(4/3 + 4) pi
5 1/3 pi
16.75...
call it 17 cubic feet.

a sphere and a cylinder
what difference does it make to cut the sphere in half
I think the question is a bit naff
(and in feet too ...what quaint units)

since the ends are actually parabolic, not full hemispheres, it would be easier to match it to a commercial tank, try to find it here http://www.mantank.com/products/dot_propane/200_420_gas.htm
