Correct!
Your answer, R x (rad-3)/2,
equals R x 0.866...
and multiplying by 2 to get both sides of the chord
yields R x 1.732...
Incidentally, the sine of 60 degrees is also (rad-3)/2 so your result confirms the CRC formula.

- Question: how do you find 3 points on a plywood circle 120 degrees apart, without a protractor? (n/t)
- Without a template, you put your anchor bolts in. Drill out the plate.
- Yet another method
- Here you go, have a protractor:
- If I remember enough geometry...
- Cut a circle out of paper, exactly the same size as your plywood circle
- Yes, there is a way!
- So... tell us what you're building! (n/t)
- Why can't you use a protractor?
- It's impossible
