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

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

hello i am doing good for you that it's summer in your country or state ; )

also, thx a lot for the points : )

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
