Given : Radius = 5cm and altitude OX on chord PQ , OX = 3 cm
To find : Length of Chord PQ
Solution:
Radius = 5cm
O is center of Circle
=> OP = OQ = Radius = 5 cm
OX = cm
OX ia altitude on PQ
=> X is mid point of PQ
=> PX = QX = PQ/2
PX² = OP² - OX²
=> PX² = 5² - 3²
=> PX² = 16
=> PX = 4
=> PQ = 2 * 4 = 8 cm
Length of Chord PQ = 8 cm
