Hey there Caleb,
So, by starting off, we need to know the formula that we are going to use by answering this question above.
The formula that we are use in the problem above would be . . .
[tex]r = \frac{C}{2 \pi } [/tex]
So, by using this formula, this would be able to help us along the way to determine the correct answer to this question.
Your correct answer would be [tex]\boxed{37.7}[/tex].
[tex]6= \frac{120}{37.7 \pi } [/tex]
I really hope this helps you!
