| Transparent Background Problem |

Hi guys,
I'm new to this. I've been using the following method to cut a product out of a picture and make the background transparent:
Add Alpha Channel
Select Product image i want to keep using Free Select
Feather Image by 5,000 px
Invert
Clear
and this method has been working great until today where I have carried out the above method but when I put 5,000 px in Feather it won't accept it and keeps changing it to "50.00" px and then when I Invert and go to clear it makes the image a little transparent but I can still see the background. I have to keep pressing Clear 10 times until the image background is completely gone and then export but the image quality suffers and I'm wondering what I am doing wrong?
To try and fix this I have reinstalled GIMP twice (to a different directory the second time) and gone to Edit -> Preferences and Reset everything but I'm still having the same problem.
HELP! And thanks in advance.

EDIT - after posting, I realized I posted to the wrong forum. I'll try to contact the Admins to get it moved/removed.
Hi all, I'm using GIMP 2.10.8 on Mac 0S Sierra 10.12.2.
How can I create a series of lines that radiate from the canvas center, and mark out equal segments of a circle? (I've put in place a horizontal and vertical guide, with the snap to guides turned on)
I've drawn two line segments, one that crosses the center of the canvas, and one that begins in the center of the canvas. But the rotate tool is based on a point in the center of my line segment.
ps - there is a video that shows how to do something like this, but there is no sound (!) and my eyes aren't good enough to see what s/he is actually doing. (I hope in this case it's ok I'm posting a link, I think it's the best way to explain)

Thank you very much

| individual canvas size for layers? |

I'm working on a huge (14'x8') image that I'm slicing down into individual standard US Letter size fragments. I need to export the layers created this way to a PDF with each layer as a page. When I do this, the individual pages it creates seem to keep the main canvas size of the huge image as the page size, rather than the boundary of each layer. Is there anything I can do to make each layer's boundary the size of its page in the PDF? I'd like to avoid having to manually crop each page, since there are 224 of them.
Thank you in advance!
