This describes how to set up the problem

http://en.wikipedia.org/wiki/Solid_of_revolution

This shows how to use the setup on that page for the rotation around the x axis.

In[1]:= Pi*Integrate[Abs[(x^2-4x)^2-0^2],{x,0,4}]

Out[1]= (512*Pi)/15

Using the Wiki page and this example you should be able to figure out how to do this around the y axis.

Please check this carefully to make certain I have not made any mistakes.
