1. ## Find the volume

Hi to all
I've got a trouble with one question. Could anybody help me. Appretiate it.

The question sounds:

Find the valume generated by the given functions of y=1+sqrt(x) and y=0 from x=1 to x=5 about the line x=-2.

Thank you

2. You can use shells.

$2{\pi}\int_{1}^{5}[(2+x)(1+\sqrt{x})]dx$
