Find the volume V of this solid that is rotating the region bounded by the given curves about the xaxis: y=4/x y=0 x=8 x=16. So far I have the integral pi (4/x)^2  (0)^2 dx. Do I foil 4/x from here? If so, how do I go about doing that? In other problems I've done, that's what I've done from here. Or do I take the antiderivative for the next step?

I put 16 in for x and then squared that and divided by 16. and subtracted that and what I got for doing the same for 8
