A graphing calculator is required for this problem. Let A and S be the regions in the first quadrant shown in the figure. The region A is bounded by the x-axis and the graph of y = 4sinx. The region S is bounded by the y-axis and the graphs of y = 3 - 2x and y = 4sinx. 5 4 3 2 IS 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 A 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)
