Is it possible to extract a few pages from a large PDF file in order to create a new file?

I need to email a few pages from a large PDF file and I was wondering if anyone here knows of a tried and true way of doing it. I found this by doing a Google search but it didn’t work for me. I followed all the steps but when I click on the menu button (step 4), there is no option to “Extract Files” as in the picture.
