Question

Given a circle of radius 5cm and center O. OL is drawn a perpendicular to a chord AB. If OL=3cm,then find the length of chord AB.

Answer 1

Answer:

4is the answer because 3,4,5 ARE PITHAGORIENT TRIPLETS THE HEIGHT =3Cm the hypotenuse will be 5cm and the base will be of 4Cm

Answer 2

Answer:

8 cm

Step-by-step explanation:

Given,

r= 5 cm

OL=3 cm

Now by Pythagoras Theorem,

r²=OL²+AL²

5²=3²+AL²

25=9+AL²

25-9=AL²

16=AL²

AL=√16

AL=4 cm.

Now, length of chord AB=4+4

=8 cm.
