Finding Volume of Solid Rotated X-Axis

  1. Mar 5, 2007 #1
    Ok, i'm supposed to found the volume of the solid that is created after rotating the line f(x) = 2x-1 around the x axis. The limits are y=0 x=3 and x=0. I've been trying for about and hour, and keep getting the answer: 46.0766. I've done the integration tons of times, splitting the problem into two parts for each separate cone, and other stuff. I just can't seem to get the right answer, please help.

    Tell us how you set up the integral.
