Consider the region R0R_0 under the line y=xy = x on the interval 0≤x≤30 \le x \le 3 and above the x-axis. The region is revolved about the horizontal line y=2y = 2, producing a solid. a. Part 1: (a) Determine the xx-value where the line y=xy = x intersects the axis of rotation y=2y = 2. b. Part 2: (b) Explain why the solid must be decomposed into two parts, one for 0≤x≤20 \le x \le 2 and one for 2≤x≤32 \le x \le 3, when writing an expression for its volume. c. Part 3: (c) Write the two definite integrals with respect to xx that, together, give the volume of the solid. d. Part 4: (d) Evaluate the integrals and state the exact volume.
