The volume can be broken down into two integrals corresponding to the two curves.

Since it's with respect to the y axis, need to make all the curves in terms of y, and change the integral bounds to be in terms of y, not x.
Since it asks for 4 d.p. you can just push calculator once you obtain the integrals and correct bounds.
