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

Step-by-step explanation:

The chord of a circle will act as a hypotenuse of a right angle triangle.

So considering the chord as a hypotenuse and the radius of the circle and the distance of the chord from center as the sides of the triangle, we'll apply the Pythagoras theorem:

a^2+b^2=c^2

20^2+20^2=c^2

400+400=c^2

800=c^2

c=√800

c=28.2 cm

Answer 2

Answer:

not possible to find the length of chord as radius is hypotenuse and hypotenuse can never equal to any other of its side.
