Thread: Volume of a solid obtained by revolution

Can anyone help with this one:

The region bounded by y=2+sin x, y=0, x=0 and 2pi is revolved about the y-axis. Find the volume that results.

I know what the graph looks like, I just don't know what to do on this one. Which method do I use--disks or washers (the topic of the homework)

This would be ideal for the shell method you obtain simply :

2pi integral[{2x+xsin(x)}dx] integrated from 0 to 2pi

personally I wouldn't touch it with disks and washers
