I'd like to know how to setup the integral so that I can find the volume of the solid generated by revolving the region between: $y=x$ & $y=\sqrt{x}$ about the line $y=1$ (P.S. No need for a full answer. I just need the proper setup of the integral where I need every part of the integral identified for me to follow what's going on).
Part of the difficulty lies in my poor imagination so if the problem solver can link me to an online utility that can help me see this solid of revolution very clearly then I will be very thankful :)
