Question

find the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis

Answer 1

\[y=1/x \]
\[x \ge1\]
\[y=0\]

Answer 2

please how me why the area of the surface is infinite

Answer 3

The integrals look like what?

Let's see the Volume Integral...

Answer 4

i used the shell method \[2\pi \int\limits_{1}^{\infty} (1+x)(1-1/x)dx\]

Answer 5

the answer came out to be pi not sure if thats correct or not and i don't how to show the surface area is infinite

Answer 6

Hmmmm surface area isn't working out nicely for me :(
I'll show you what I've got so far...
