Best Answer

The key facts: 1 gallon is 231 cubic inches.

There are 12 inches in a foot.

The formula to use is v = Length * pi * r2

A conversion to gallons will be the last step.

v = (60 * 12) * 3.14 * 152

v = 720 * 3.14 * 225 = 508,680

v in gallons = 508,680 / 231 = about 2,200 gallons. Your instructor might want a more precise answer using a more accurate value of pi.
