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

y=x

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?
