5. A graphing calculator is required for this problem. Let R and S be the regions bounded by the graphs of x} = sin{x} and 9H) = x?_1. as shown in the gure. 4 y 3 S 0 X R -1 -2 -3 45 4 -3 2 -1 0 1 2 3 4 5 Part A: Find the area of R + S. Part B: The region R is the base of a solid. For this solid, each cross- section perpendicular to the x-axis is a semicircle. Find the volume of this solid
