This is a question on one of my past exams that I'm trying to do...
the question says to find the volume of the regions bounded by y=x^2-2 and
rotated about x=2
I was thinking that the radius equalls (2-x) [I'm not entirely sure about this]
and the height equals (x-(x^2-2))
all of them multiplied together with PIE under the integral from -1 to 2
is this correct?
