Consider the solid obtained by rotating the region bounded by the given curves about the line x = 1.
$x=y^2,x=1$ Find the volume V of this solid.
Sketch the region, the solid, and a typical disk or washer.
I have been following this example as a guide; however, I keep on getting the wrong answer.
$\pi\int\limits_{-1}^{1}{(1-y^2)^2dy}={16\over15}$
Any suggestions?
