I need help with these two problems. If you could please explain the solution, I would appreciate it.
1.Use cylindrical shells to compute the volume. The region bounded by y = x and y = x2 - 2, revolved about x = 3
2. A solid is formed by revolving the given region about the given line. Compute the volume exactly if possible and estimate if necessary. Region bounded by
y = sec x, y = 0, x = -π / 4 and x = π/ 4 about
( a) y = 2
( b) the x- axis© BrainMass Inc. brainmass.com December 20, 2018, 11:59 am ad1c9bdddf
The solution gives detailed steps on finding volume using definite integral.
