Let R and S be the regions in the first quadrant shown in the figure. The region R is bounded by the x-axis and the graph of y = 3sinx. The region S is bounded by the y-axis and the graphs of y = 3 - 2x and y = 3sinx. 5 y 4 3 2 S R X -1 - 2-2 -1 0 1 2 3 4 5 6 Part A: Find the area of S. (15 points) Part B: Find the volume of the solid generated when R is revolved about the x-axis. (15 points) Part C: Write, but do not evaluate, an integral expression that can be used to find the volume of the solid when S is revolved about the x-axis. (10 points)
