@mathmate So I need to use circumference? Is that what you're saying?

Sorry, I give hints, sometimes a few steps, and examples.  I do not dictate answers.
If you find my hint useful, you should be able to select the answer based on your judgment.

It is circumference for anyone curious.

o-b-server · Answer

It's because the circumference is the length of the outside of the circle, so you need to use it for rotations of a circle.

Exactly!  Well done!
