20A-20E
20 a) sketch the region bounded by the following. b) state which method you are using (disks, washers 20A) The region bunded by y-r, x = 2, x = 3, and the x axis, is rotated about the x-axis. Find the volume of the figure so formed. Again, set up integral only 2015) Consider the region R bounded by y = x2 +3x and y =x . Find the volume of the solid formed when this region or shells), c) set up the integral (you dont need to evaluate it) R is rotated about the x -axis. Again, set up integral only 20C) Consider the region from part B). Instead rotate R about the y-axis. Find the volume of the solid. Again, set up only. 20D) The region bounded by the x-axis and y = 2x-x2 is rotated around the vertical line x-3. Find the volume of the solid so formed. Again, set up only. 201) The repon bounded by y-x, and y-2x2 is rotated about the y-axis. Find the volume of the solid so formed. Again, Set up only
