I'm asked to find the volume of the solid bounded by the curves x=1+y^2 and y=x-3, rotated about the y-axis.

I have a general idea of how to start the problem off, but I'm not sure how to find the interval that I need to work with...

1. First put each equation in the form x= .

There should be two intersections between the two equations, which will define the bounded area.

2. Okay, so when I write the integral, is it in terms of x or y?

3. It should be in terms of y, because you are rotating around the x axis. (That's why you have the form x = ).
