## Homework Statement

Find volume of the solid generated by revolving the region bounded by x = y^2, x=4about the line x = 5

## Homework Equations

the washer method from c to d ∏∫ R(y)

^{2}- r(y)

^{2}

## The Attempt at a Solution

I set r(y) = 1 and R(y)= y^2

and got the integral from 0 to 2 of ∏∫(y^2)^2-(1)^2

I got an answer of 16.96 but i know this is wrong because the back of the book gives a different answer. Please tell me where I went wrong.
