Consider a solid of revolution obtained by rotating a region around the x-axis. Select all the True statements below:

A. When using the disk method, we cut the region into small slices parallel to the -axis. B. The volume of the solid of revolution can be interpreted as the limit of Riemann sums. C. When using the shell method, we cut the region into small slices parallel to the -axis. D. When using the disk method, we cut the region into small slices perpendicular to the -axis. E. When using the shell method, we cut the region into small slices perpendicular to the -axis. F. The shell method will always result in a less complicated integral. G. The thickness of the slices will be for both methods.
