Continue doing this till you have closed in the circle.
Now you can measure the length of the octagon lines where they meet.
There y' go

I wish you would have said "This is they way I would have done it before I found out how easy it is to do your way."
Maybe if we see how long it takes each of us to do a sample problem might just have you "see the light". OK we have a planter that is 12" in Dia. and we want a nice cedar 12 sided box made to fit around it.
On your mark
ready steady GOOOOOO
OK the radius is 6 so 6 divided by the 1.8660 is 3.215 ..... I'm done! I guess that was oh maybe 15 seconds..... please post your time when you finish........
Yes you can do a drawing, yes you can make it by guessing then trimming the parts and maybe another half dozen ways but this is a very fast way and a very easy way.
Now get out your calculator and give it a try!!!!!!!
