Question

Calculate the length of a chord which is at a distance of 12 cm from the centre of a circle of radius 13 cm.
Answer:​

Answer 1

Answer:

The answer is 10 CM

kaisa

By the method of hypotenuse square

let length of chord is x

(13)2=(12)2+(x)2

169-144=(x) 2

25=(x)2

(5)2=(x)2

x=5

And the hole length of chord is 5+5 =10cm

Answer 2

Answer:

Here OA = 13cm ( Radius of the circle )

OS = 12cm ( distance from the chord )

And AS = 1/2 of AB
