Find the length of the chord of a circle where the radius is 7 cm and perpendicular distance is 6 cm.

  • 0

Using the chord-length formula or the Baudhāyana–Pythagoras Theorem, the half-chord measures √13 cm. Therefore, the complete chord length is 2√13 cm.

    1. Draw a perpendicular from the centre of the circle to the chord. It bisects the chord into two equal parts. Applying the Baudhāyana–Pythagoras Theorem to the right triangle, the half-chord is obtained as √13 cm. Doubling this value gives the full chord length. Therefore, the required chord length is 2√13 cm.
