    I'll give it a try: y=2 sin x, y = sq rt 2; (1) 2 sin x = sq rt 2; therefore x = pi/4. Radius big circle 2, radius small 2 - 2 sin x. Therefore, V = integrand from 0 to pi/4 of (2^2 -[2 - 2 sin x]^2)pi dx. I will ask around tomorrow if I am right. Been a while since I did it. Btw this is washer method.
