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

C = 2Ï€r

However, since that option isn't listed, the closest response you have is:

C = π2r

which appears to be a typographical error for the intended formula (C = 2Ï€r).

Please check if there might be an option "C=2Ï€r" available. If not, then none of the provided formulas are correct for the circumference.
