(0, 6) (Calculator allowed) (2, 0 3. In the figure above, R is the shaded region in the first quadrant bounded by the graph of y = 4In (3-x), the horizontal line y = 6, and the vertical line x = 2. a) Find the volume of the solid generated when R is revolved about the horizontal line y = 9. b) The region R is the base of a solid. For this solid, each cross section perpendicular to the x- axis is an equilateral triangle. Find the volume of the solid. c) Find the perimeter of region R
