You need the circumference of the plate. That's given by \[C=\pi d\]where d is the diameter. In your case,\[C=\pi \times 30cm \approx 94.248 cm\]...this assumes the question is meant to be pretty basic and not take into consideration the fact that this circumference is technically infinitesimally thin...
