At one end of a d

Answer :

Given:


Radius = OP = 5 cm


Distance of AB and XY = 8 cm



Distance of AB and XY = 8 cm


And AB is parallel to XY


PR = 8 cm


Join OB


Now,


OB = OP = 5 cm [radius]


Also,


OR = PR – PO


OR = 8 cm 5 cm


OR = 3 cm


By Pythagoras theorem in ORB,


OB2 = OR2 + RB2


52 = 32 + RB2


RB2 = 52 – 32


RB2 = 25 – 9


RB2 = 16


RB = 4


Now,


AB = AR + RB


AB = 2RB


AB = 2 × 4


AB = 8 cm


Hence, Length of chord = 8 cm
