Find the volume of the solid formed by rotating the region enclosed by

, \ , \ , \

about the y-axis.

I'm just at a loss here as to how to proceed. It's a change about the y axis so I assume the functions have to be done with respect to y, but how can that be done for the first one, $\displaystyle y = e^x + 1$?

Any help on how to begin would be appreciated.
