The question does not have enough information, as you will need the length of the pipe to be able to calculate the maximum volume which can encompass it.

In order to figure it out, think of the pipe as a cylinder, where the formulaV=pi*r^2*l will give you the volume of water.

looking at the units,assumingyou are using common units and 9 inches relates to the inside diameter of the pipe. (if it isn't, and your looking at schedule 9' pipe, you'll need to see a chart).


Volume= (pi)* (9/2 inches)^2*(length of pipe in inches)

which will give you a volume in inches^3.


looking at a conversion between inches cubed and gallon you get

1 cubic inch= 0.004329gallons
