Expert Answer
Circumcentre O of circumcircle of ΔABC is the point where the perpendicular bisectors of all three sides meet.
 
Hence OD bisects side BC . Hence CD = 12 cm
 
OC is radius of circumcircle , hence OC = 13 cm
 
ΔODC is right angled triangle and angleODC is right angle.
 
begin mathsize 14px style O D space equals space square root of O C squared minus C D squared end root space equals space square root of 13 squared minus 12 squared end root space equals space 5 space c m end style
