Since everything is in feet or cubic feet, you can just focus on the numbers.

volume of cylinder tank: %2822.5%29pi%2A%289%2F5%29%5E2 and notice diameter is cut in half to use radius.

How many of the 9.5 are in the %2822.5%29pi%2A%289%2F5%29%5E2 ?

HowMany=%281%2F9.5%29%2822.5%29pi%289%2F5%29%5E2
This will be a rational number of pi, but can be approximated to highlight%287.674%2Api%29 barrels. This is about 24.1 barrels.
