So there re 12 inches in 1 foot...so it would be 12*8=96 inches

3.14*12=37.68*12=452.16*96=43407.36

then I have to convert to cubic feet.

43407.36^1728= 25.12 cubic feet

IS this correct

**Ms. Sue**, Tuesday, September 30, 2008 at 9:38pmIt seems to me that it's easier to convert the radius to 1 foot and then solve the problem.

**PsyDAG**, Wednesday, October 1, 2008 at 1:30pmThere are no cubic feet in a foot. However, there are 12^3 (12 * 12 * 12) cubic inches in a cubic foot.

For the volume of a drainage pipe (which I assume is circular), you need to multiply the area of a circle (Pi * r^2) by the length. It doesn't look like you have done that.

I hope this helps a little more. Thanks for asking.
