# The length of a c

Answer :

Given PQ = 4cm, Distance from the Center is 2,1cm

PQ = 2 PD

Perpendicular from the center of the circle to any Chord bisects it in two line segments

⇒ PD

⇒ PD = 2cm

In O PD , Using Pythagoras Theorem

⇒ OD^{2} + PD ^{2} = OP^{2}

⇒ OP^{2} = 2.1^{2} + 2^{2}

⇒ OP^{2} = 8.41

⇒ OP = 2.9cm
