1. ## urgent, calculus problem

The problem is as follows

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

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

Find the volume V of this solid."

For a solution I get

5*pi*ln(2)

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.

$V = \pi \int_8^{16} \frac{25}{x^2} \, dx$
