Just divide each term individually by 2.

And lol, SRSLY?
Radius is definitely not circumference over 2.
Who in the world made this question? XD

Are you sure it isn't diameter?

1645323 · Answer

B? yes im pretty sure , this is an online class and my teacher messes up sometimes so its probably another mistake

what would the answer be for diameter?

terenzreignz · Answer

B, yes, that's correct.
Interesting teacher.

terenzreignz · Answer

No, what I meant was that the radius can be found by dividing the DIAMETER by 2, NOT the circumference.
