Concept explainers
Washers vs. shells Let R be the region bounded by the following curves. Let S be the solid generated when R is revolved about the given axis. If possible, find the volume of S by both the disk / washer and shell methods. Check that your results agree and state which method is easier to apply.
44. y = (x − 2)3 − 2, x = 0, and y = 25; revolved about the y-axis
