Let AB be the chord of the given circle with centre O and a radius of 10 cm.
Then AB =16 cm and OB = 10 cm
From O, draw OM perpendicular to AB.
We know that the perpendicular from the centre of a circle to a chord bisects the chord.
∴ BM = (162) cm=8 cm
In the right ΔOMB, we have:
OB2 = OM2 + MB2 (Pythagoras theorem)
⇒ 102 = OM2 + 82
⇒ 100 = OM2 + 64
⇒ OM2 = (100 - 64) = 36
⇒ OM=
√36cm=6 cm
Hence, the distance of the chord from the centre is 6 cm.
