1.)Consider the given curves to do the following. http://www.webassign.net/www14/symIm...e15fdf4024.gif

Use the method of cylindrical shells to find the volumeVof the solid obtained by rotating the region bounded by the given curves about thex-axis.

2.)Consider the given curves to do the following. http://www.webassign.net/www14/symIm...7bb8fe6763.gif

Use the method of cylindrical shells to find the volumeVgenerated by rotating the region bounded by the given curves aboutx= 4.

3.)The region bounded by the given curves is rotated about they-axis. http://www.webassign.net/www14/symIm...8e524ed900.gif

Find the volumeVof the resulting solid by any method.

my main problem when doing these problems is i think im setting it up wrong at the beginning so can someone just help me set up these problems up to the point to the integral. Thanks in advance!
