Question

how do u find the circumference of a circle without the diameter or radius just then arc length?

Answer 1

In order to find the circumference you will use the arc length to find radius.

Use the equation

arc length L =  r*Θ , where  Θ is in radians.

Re-arrange the equation to get r = L / Θ

Finally use radius to solve for circumference using

C = 2 π r
