This sounds like homework?

The formula for the volume of a cylinder is: PI * Radius squared * length

Since we used inches, the answer is in in^3 (cubic inches), but I'll assume you want the answer in gallons (US). There are 231 in^3 in 1 gallon (US), so cubic inches / 231 cu. in./gal = gallons (US).
