## Homework Statement

Find the volume of the solid generated where y = 1/x for 1<=x<=5 is rotated about the x axis.

## Homework Equations

I = r^2 dm, sqrt(1 + (dy/dx)^2) dx,

## The Attempt at a Solution

So I have found the length of the curve and can henceforth find surface area and so on but I cannot figure out the step to take to get to volume, I understand that it probably isn't too difficult after the first part, so does anyone knw what the relevant formula is to solve for this, any help much appreciated :) btw solid will b the shape of a spinning top in a way ty :)
