Hi all. I am a recent Chemical Engineering graduate, and I recently was program recommended into the Naval Nuclear Engineering Program. While going over a study guide for my technical interviews coming up, I came across this problem, and my mind went blank! It goes something like this: 1. Plot both y=x^2 and y=x^3 on the same graph, but only to 1. 2. Determine the area inbetween both functions using integration. 3. Imagine this space inbetween the functions was rotated about the x-axis. What will the volume of this region be. While both parts 1. and 2. are quite trivial, I couldn't seem to figure out the the last part of the problem! Any help would be greatly appreciated. Thanks!
