NEED SOLUTION!!!!

This is too easy to write down the answer here. You should study some examples in your text book, and you can solve this by yourself.

TOO EASY?? I think you didn't understood the problem.

In general, the volume V of the revolved figure bounded by

y=g(x),
y=f(x),
x=a, and
x=b
(where f(x)>g(x) for all x such that b>x>a)

is given as

V= pi * integeral{from a to b}(g(x)*g(x) - f(x)*f(x)) dx.
(Do not forget multiplying pi.)

Thanks a lot.. But can you also give me an answer? :-)

I may be misunderstanding your question.
Could you restate the problem more clearly?
The point is what the axis of the rotation is.
