Question

Radius of a circle is 73 cm. The distance of the chord from the centre is 48 cm. Find the length of the chord.​

Answer 1

Step-by-step explanation:

given that -

radius , r=73

distance from center, p=48

p is the perpendicular dis from centre to the chord.

to find - length of the chord

let the length of chord be 2x.

by using Pythagoras theorem,

(r) ²=(p) ²+(x) ²

(73) ²=(48) ²+(x) ²

5329=2304+x²

x²=3025

x=√3025

x=55cm

length of the chord is 2x=2×55

=110cm.
