Question

A CIRCLE OF RADIUS 5 cm with centre o is given drew ol perpendicular to the chord ab if ol =3cm the find the length of the chord ab
​

Answer 1

Answer: 8 cm

Step-by-step explanation:

Given,

r= 5 cm

OL=3 cm

Now by Pythagoras Theorem,

p²=OL²+AL²

5²=3²+AL?

25=9+AL²

25-9=AL²

16=AL²

AL=V16

AL=4 cm.

Now, length of chord AB=4+4

=8 cm.

Hope it helps you!!!
