Cylindrical shells?

Question

Use cylindrical shells to find the volume of the soid that results when the region enclosed by y^2=8x and x=2 is revolved about the line x=4

I got the answer (64(4square root 2-1)pie)/5 , is that correct??

Answer 1

Volume = 2 pi integral 0 to 2 p(x)h(x) dx where
p(x) = distance from axis to x = (4-x)
h(x) = sqrt (8x)
