the respond is 50.24 cu. ft. The formula for the component of a circle is Pi x D, which for that reason is 3.1416 X 2. Multiply that via 8 to get the quantity. i anticipate your diameter value is the interior diameter. wish this facilitates.

The equation is pi Rsquared x length
24"=2'd R=1'
3.14(1x1)8
3.14 x 1 x 8 =25.12cf

Every 33 inches of pipe 24" around is 55 gallons.
Yours would hold 160 gallons. 160 gallons is roughly 24.89 cubic feet. I think my math is right.

(piR^2) x H
43429.376 Cu. In.
25.13 CU feet. the trick is that 1 cubic foot is 1728 cubic inches (12cubed or 12^3)
