Find the length of a chord which is at a distance of 15 cm from the centre of a circle of radius 25 cm.

Answer :

The figure is given below:



AE = 15cm


AB = AC = 25cm


From Theorem: A circle with radius r and a chord of length l which is at distance d from the centre, follows the equation,



Here d = 15cm and r = 25cm




l = 40cm


Hence the length of the chord is 40cm.
