@ForeverMozart yeah I just figured that out, would have to show y as a function of x. My fault.

@ForeverMozart I see what you did, however you did your area calculation through vertical slicing which is perfectly fine, and mine is through horizontal slicing, which is correct too. I guess I'll look into the washer method. Thanks for the suggestion!

How can I translate that to something legible instead of $_int etc

Called a math chatroom, ask for help with math, nothing happens. Go figure. Thanks for the help (not really), I guess I'll try more to look it up or ask on math stack exchange

Hi guys, I'm new here, I had a question about revolving regions around axes. I am asked to revolve the region bound by y=(x^3)+1, y=2, x=0 about the line y=-1. So I know how to find the area of the region, which is done by: http://i.snag.gy/GP5pP.jpg
but how would I find the volume if it was revolved around y=-1? What would the volume be?
