Answer:

8.6 km

Explanation:

The circumference of a circle is given in terms of its radius as ...

C = 2πr

Then the radius can be found from the circumference using ...

r = C/(2π)

Filling in the given values, we find the radius to be ...

r = (54 km)/(2·2.14) = (54 km)/6.28 ≈ 8.59873 km

The radius is about 8.6 km.
