# Thread: Tricky solid of revolution

1. ## Tricky solid of revolution

Consider the solid obtained by rotating the region bounded by the given curves about the y-axis.
Find the volume V of this solid.

Im working on this problem with my roomate and i just want to clarify if i can use the disc method and set up the integral with integration limits e^4/2 to e^6/2

EDIT: Nvm think in terms of dy

2. Yes, the integral is with respect to y and so the limits of integration are from y= 4 to y= 6.
