It's a 15" diameter but you don't know the diameter or radius?

If you have a piece of string, you can run it along the circumference, mark the length, fold that into thirds, and retrace.

You can try this search: and try 180 or 90 for your angle. Once you get a 30 or 60, you'll be good with the steel ruler.

My bike runs on dihydrogen monoxide.
I like to use these acronyms
