I've been working on with the area of the region in my calc II class, and now have to deal with the volume.

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line.
$$y = 7\sqrt{49 − x^2}, y = 0, x = 2, x = 3$$ about the x-axis

I was able to draw the graph, but can't set up the integral.
Any help would be appreciated.
Thanks!
