How do you use the disk method to find the volume of the solid formed by rotating the region bounded by #y = 2x# and #y = x^2# about the y-axis?
I can't get both curves on one graph, but I'll assume you can graph the line and the parabola.
Rotating around the
The representative slice is horizontal with left end (little radius: r) on the line
The thickness of the disk will be
