The correct formula to find the circumference of a circle when the radius is given is:

**C = 2πr**

However, since that option isn't listed, the closest and relevant good option is:

**C = πd** (since \(d = 2r\))

None of the options you provided are perfectly accurate, but if we could define one correctly it would be C = 2πr.

If you have an option for **Circumference = 2πr**, that would be the accurate one.
