Having troubled graphing this its going to be a bowl shape i think, the question is like so:

The finite region bounded by curves $\displaystyle y=x^2$ and $\displaystyle y=4$ , is rotated around the line y=-2 , find the volume of the resulting solid.

Okay is this gonna look like a bowl, with a inner radius and outer radius am gessing inner radius will be 2 outer will be 2 + x^2 please correct me if am wrong thank you !!
