The circle's radius is 3. That is because the formula for the circumference of a circle is 2(pi)r. Divide 18.84 by 2 then divide that by (pi). Hope this helps!

We can use the circumference formula to find the radius.

C = 2πr
18.84 = (2)(3.14)(r)
18.84 = 6.28r
3 = r

So the radius of the circle is 3 kilometers
