The question is
Given a curve C whose equation is give by y=(12/(x + 3))- 4,
find the region bounded by C, the line x=0, the line x=3 and the line y=8 is rotated through 360 degree about the y-axis. Calculate the exact value of the volume generated.
My solution is here

However, this solution is not the answer in the textbook. The anwser in the textbook is
36pi(1+2ln2).
Can someone show me where am I doing wrong?
