Yes. now an arc is a segment of the circumference correct?

yes

And if I want to know the circumference I need to know the sum of all the arcs, so 1 arc is 2 (pi) and I have 12 arcs. I need to add 2( pi) 12 times.

24(pi)?

  • retirEEd
2 (pi) times 12 = C but you don't need to multiply the pi 2 (pi) * 12 = C = Pi * D Solve for D opps you want radius so divide D by 2 sorry

You are ahead of me. 24 pi = C = 2 pi r 24 = 2 r r = ?
