i missed this lesson, skiing that day, and am wondering if im doing this right
the question is:
Find the volume of the solid that results when the region enclosed by the given curves is revolved around the given axis.
y=√x, y=0, x=0, x=4; about y=2
i wrote it as pi times the integral, from 0 to 4, of 2^2-(√x)^2
and got 8pi
can anyone confirm, or refute that? or offer some help
