This problem is an exercise problem in our calculus class and we were tasked to find the volume using the Washer method. I already sketched it and know what the figure will look like if revolved: like a coin on its side with a funnel-shaped hole through it. But the problem is I don't know what is R (outer radius) and r (inner raidus) are. Is it R=x^2-2x+y=3, r=4-x?
