Given that,  Radius of circle (OA) =13cm  Distance of Chord from centre (OC) =12cmFind AB=?  Draw OC⊥AB  We know that  The perpendicular from centre to chord bisects the chord  ∴, AC=CBand AB=AC+CB=?  Now in ΔOCA, by Pythagoras theoremOA2=OC2+AC2132=122+AC2AC2=169-144AC2=25AC=5 cmCB=AC=5 cm AB=10 cm
