Question

a chord of a circle of radius 10 cm subtends a right angle at the centre. find the length of the chord in cm​

Answer 1

Answer:

10√2

Step-by-step explanation:

Hence if the chord subtend right angle then a right angled triangle is formed between chord and two radius of circle.

So by using pythagoras theorem,.

10²+10²=length of chord

Hence length is 10√2.

Thanks for asking the question.

Mayyou will understand politely.

Answer 2

Pythagoras theorem,

10²+10²=h^2

h=$\sqrt{200}=10\sqrt{2}$
