The "27" can be either the radius or the diameter. The main number that is needed is Pi. Pi is equal to 3.141592654....... Therefore, the formula is as follows: C=2(Pi)(r) or C=Pi(d).
C=2(Pi)(27) --> C=169.6460033...=169.65
C=Pi(27) --> C=84.82300165...=84.82
The answer can either be 169.65 or 84.82 depending on the situation.
