Q5 of 9 Page 32

The radius of a circle is 13 cm. The length of a chord is 10 cm. Find the distance of the chord from the centre of the circle.

Given: radius of a circle = 13cm

Length of chord = 10cm


By, Given information we will draw a circle.



Given: radius AB = 13cm


chord BC = 10cm


Let, us draw a perpendicular bisector AD of BC

Thus,


Also, since AD is perpendicular bisector of BC


Therefore,


By Pythagoras formula







Thus, distance of the chord from the centre of the circle is 12cm
