the region bounded by y = 1/2(x2)^2 and y = 2 about the yaxis.
I get 64 pi/ 3 as the answer...and there's no way to verify this problem. Can some1 please try it?

Sorry it took me so long to get back to you; I used the shell method and did the integration:
(integral)(0 to 4)2pi*x(2  (1/2)(x  2)^2) dx and came up with 64pi/3 also. We must be right!
