Question

Radius of circle is 20 cm. Distance of the chord from the centre of the circle

is 20 cm. Find the length of the chord.​

Answer 1

Answer:

00cm

Explanation:

The chord is at 20cm distance from centre and radius is also 20cm means the chord is on the circumference itself that is as a dot in the circle.

So length of the above is 00cm.

Answer 2

THE QUESTION IS INCORRECT DEAR, because radius will not be equal to distance. If you use pythagoras theorem, this is what will happen:-

OM² + AM² = OA² (radius)

20² + AM² = 20²

BUT, AM = √20-20

AM = √0, WHICH IS NOT POSSIBLE.

Please check the value of the distance of chord from centre. It must be lower than the radius.
