Hello everyone. I'm having trouble solving this problem:

Finding the volume by revolution of y=3-2x, rotated around the y-axis. I have the integration set up as $\displaystyle pi* ((y-3)/-2)^2 dy$ from $\displaystyle -3/2...3/2$ . Did I set this up wrong since I'm dealing with a straight line and not a curve? I can't seem to get the answer that my book gives.

Thanks in advance for any help!
