Question

Radius of a circle with center O is 41 cm. Find the length

Of the chord if the chord is at a distance of 40 cm from the centre.​

Answer 1

18 is length of chord

Step-by-step explanation:

by Pythagoras theorem-

(radius)2=(distance of chord from the centre )2+(lengths of half chord)2

(41)2=(40)2+(X)2

X2=481-400

X2=81

take square root

X=9

so, chord= 18
