The problem is as follows

"Consider the solid obtained by rotating the region bounded by the given curves about thex-axis.

y=5/x, x=8, x=16, y=0

Find the volumeVof this solid."

For a solution I get

pi(5ln(16)-5ln(8))

Is this correct? I am asking because i've done the problem multiple times and am submitting it electronically for homework but it won't accept it or any other simplified form.

Thanks in advance.
