:
The vol of a cylinder V+=+pi%2Ar%5E2%2Ah
:
change 24" to 2 ft
V+=+pi%2A2%5E2%2A100

The pipe is in a shape of a cylinder, so you use the formula V=2%2Api%2Ar%2Alength
where the radius is 24 inches (24%2F30 feet) and the length is 100 feet.
Solution is 502.65.
Since it is different, maybe the person who gave you the answer miscalculated, so I would double check with the teacher or a classmate.
Hope it helps.

Vol+=+pi%2Ar%5E2%2Ah
Vol+=+pi%2A4%2A100
Vol =~ 1256.637 cubic feet
