The graphs of y = 2, y = g(x) (solid) and y - h(x) (dashed) are shown; the graph is not drawn to scale. A B Region One The points labeled are A = (3, 2), B = (8, 2), C = (6, 1), and D - (1, 0). Suppose Region One is revolved around the y-axis. Select the expression(s) needed to find the volume of the solid of revolution formed when the region is revolved around the y-axis. 0 27z(2 - g(z)) dx " / 2 7 2 ( 2 - h ( 2 ) de 0 27z(h(z) - 9(z)) di - 7 ( 2 2 - (9( z ) ? ) de 7 ( 22 - ( h ( z ) ? ) due
