# Thread: Volume of function rotated around a line (non-axis)

1. ## Volume of function rotated around a line (non-axis)

I am having a big problem trying to find the volume of a function by wrapping it around a line - as opposed to the usual way of wrapping it around the x or y axis.

Say I have f(x)=x^2 and I want to find the volume between a=0 and b=2 if I wrap it around a line y=2x. How would I do it?

2. So no one knows?
