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

Explanation

Given radius`=13 cm`
length of one of its chord`= 10 cm`
1/2 chord`=10xx1/2=5cm`
Distance of the chord `=r^2−l^2=13^2−5^2`
`=>169−25=144=(12)^2`
`=12cm`
The distance of the chord `= 12 cm.`
