Problem ?. [6 points] Consider a solid of revolution obtained by rotating a region R around the x-axis. Select all the True statements below: C A. When using the shell method, we cut the region into small slices parallel to the maxis. I: B. The shell method will always result in a less complicated integral. I: C. The volume of the solid of revolution an be interpreted as the limit of Riemann sums. C D. When using the disk method. we cut the region into small slices parallel to the x-exis. l: E. When using the shell method. we out the region into small slices perpendicular to the :c-exis. I: F. The thickness of the slices will be d3: for both methods. I: G. When using the disk method, we out the region into small slioes perpendicular to the tit-axis. Problem 8. (6 points) Find the length of the curve defined by y = 523/2 + 7 from x = 3 to a = 8
