Question

c is the center of the circle whose raidus is 10 cm. find the distance of the chord from the centre if the length of the cord is 12 cm

Answer 1

Answer:

Step-by-step explanation:

Chord AC = 12 cm

AB = 6 cm (Half of chord AC)

AO = 10 cm (Radius)

By Pythagoras theorem,

h² = p² + b²

AO² = OB² + AB²

10² = OB² + 6²

OB² = 100 - 36

OB² = 64

OB = 8 cm
