Thank you for the opportunity to help you with your question!

The circumfrence is the distance around the circle. By definition, pi is the ratio of the circumfrence to the diameter. the diameter is 2 times the radius. So, C=2(pi)(r). That's one of the circles. The other circle is same as the first. Multiple it by 2. so the answer is 4(pi)(r)

Please let me know if you need any clarification. I'm always happy to answer your questions.
