@Needhelpp101 Do you think it would be correct to think of this solid as a roll of toilet paper with a hollow cylinder (paper tube) in the center? If so, our task is to find the volume of the toilet paper (without the tube). So, we would find the volume of the entire roll of toilet paper and subtract the volume of the paper tube to get the only paper volume.

Subtract the volume on the right from the one on the left to get the volume of the shaded portion. |dw:1359952160987:dw|

@Needhelpp101 That's great news. Look, what did you get for the answer to this question? 2430*pi - 480*pi = or something else.
