Answer:

none of the above

Explanation:

The applicable relationship is ...

C = 2πr

Solving for r, we get

r = C/(2π) ≈58. (367 cm)/(2·3.14159) ≈ 58.41 cm . . . . no matching choice

When the problem does not include a correct answer choice, I usually suggest you ask your teacher to show you the working of it.
