Q. 24.2( 10 Votes )
The length of a d
Answer :
Given Length of the diameter = 26cm, Distance of Chord PQ From center = 5cm
Radius
Radius = 13cm
In O PD , Using Pythagoras Theorem
Hypotenuse2 = base2 + Height2
⇒ OP2 = OD2 + PD2
⇒ 132 = 52 + PD2
⇒ PD2 = 169-25
⇒ PD2 = 144
⇒ PD = 12cm
⇒ PQ = 2 PD
⇒ PQ = 24cm
