1. Let \(L\) be the centre of the circle and \(MN\) be its chord. A line from \(L\) cuts the chord \(MN\) at \(O\) such that \(\angle LON\) \(= 90^{\circ}\). If \(MO\) \(=\) 13 \(cm\). Find the length of the chord.
Answer:
The length of the chord \(MN\) is \(cm\).
2. If the radius of the circle is 13 \(cm\) and the perpendicular distance from the centre to the chord is 12 \(cm\), then find the length of the chord.
Answer:
The length of the chord is \(cm\).
