Question

FIND THE LENGTH OF THE CHORD WHOSE DISTANCE FROM THE CENTRE OF THE CIRCLE WITH RADIUS 25 IS 12​

Answer 1

Answer:

by Pythagoras theorem

x square =625-144

X square=481

x=√481cm.

Answer 2

→ X =

$\sqrt{ {25}^{2} - {15}^{2} } \\ = \sqrt{625 - 225} \\ = \sqrt{400} \\ = 20cm \\ 2x = 40cm$

So , The length of the chord is 40cm .
