## Homework Statement

Consider the region bounded by the curves y= lnx and y=( x-3)^2

Find the volume of the solid obtained by rotating the region about the y-axis

## Homework Equations

## The Attempt at a Solution

For this I solve for the x so i got x= e^y and x= (y)^(1/2) +3

and for volume equation i got :

1.47

∫ ((y)^(1/2) +3)^2 - (e^y)^2 = 12.481(pi). My answer is

0

different from the book. So can someone point out wat i done wrong and help me to get the right answer

Thank you
