its 6 cm hope it helps
We can find the radius by using the formula: C = 2(pi)(r)
We'll use 3.14 for pi.

And solve for r.

18.84 = 2(3.14)r ; Start
18.84 = 6.28r      ; Multiply 3.14 by 2
3 = r                     ; Divide both sides by the coefficient of r. Which is 6.28

So, the radius is 3 miles.
