To figure out how many gallons are in a cylinder you can use the following formula: Volume= pi x radius squared x height then divide that by 231 Note: Measure the radius and height in inches this will give you an answer in cubic inches, the reason for dividing by 231 is that there are 231 cubic inches in one US gallon. Using the above formula will tell you how many gallons your cylinder contains.
