Volume of rotation, have you done it in class recently?

is a reasonable overview. You'll need to look at section 5 so you do a rotation about the right axis, but there are some good examples.

I’ve done quite a few examples of volume of revolutions so I know what to do generally but just not sure how to set up the equations
