Question

Find the length of a chord which is at a distance of 5 cm from the centre of a circle of radius 13 cm.

Answer 1

Answer:

12

Step-by-step explanation:

distance of the chord from centre(d) = 5cm

radius of the circle (r)=13cm

let, the length of the chord be,x cm

we know that,

(radius)^2= (length of chord )^2+(distance of chord from the centre)^2

(13)^2= (x)^2=(5)^2

169=x^2+25

x^2= 169-25

x^2= 144

x=√144

x=12cm

Answer 2

Therefore:the length of the chord = 2AT

= 2* 12cm

= 24cm
