Question
The radius of a circle is 10 cm, and the length of the
chord is 12 cm. Find the distance between the chord and the centre of the circle. ÂSolution
Length of the chord = 12 cm So, half of the length of the chord = 6 cm So, distance between the chord and centre = √ {10² - 6² } = √ {100 - 36} = √ {64} = 8 cmÂ
