3. Pappus's Theorem: If a plane curve C lies on one side of a line e in that plane and is rotated about to generate a solid of revolution, then the area of that surface is the length of times the distance travelled by the centroid of C. Use Pappus's theorem and find the area of the surface obtained by rotating the circle 2? + (y - 1)2 = 1 about the line y=x-2.
