Consider the solid of revolution obtained by rotating the region inside x2 + (y – 4)² = 9 about the x-axis. Sketch a diagram of the region, the solid of revolution, and a sample washer. This a) sample washer should be labeled with an expression for the inner and outer radius. Set up, but do not evaluate, an integral for the volume of this solid using the washer b) method. c) Evaluate the integral from part b) without using trigonometric substitution.
