1. The problem statement, all variables and given/known data Use the method of cylindrical shells to find the volume generated by rotating the region bounded by the curves about the specified axis. y=x^4, y=0, x=1; about x=2 2. The attempt at a solution I know how to do the problem, except how to find the radius. Like I know if it was about the x axis then the radius would just be x. But since it's about x=2, would the radius be 2-x? If it is 2-x, why? I'm guessing it's 2-x because there was a similar problem earlier in the book that showed this being the radius when it was about x=2.
