C=π2d
upper C equals 2 d

C=πr

Pls answer with letters

Answer 1

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 response you have is:

C = π2r

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

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