can you help me check for correction

the answer i got was = 625

You want to find volume. Are you rotating the region around a line, such as the x axis, or using cross sections?

Thanks, it was not specified.

As understood, find volume.

**bobpursley**, Thursday, August 13, 2009 at 2:51pmThat is an area, not volume. Now, if that area is rotated about some axis, one can generate an volume, but the axis has to be specified. As the question stands now, it is meaningless.

I did it once for you rotating about the y axis. But in reality, it could be rotated about any axis to generate a volume.

It is hard to not get a pi if you spin something.
