Question

Radius of a circle is 20cm. difference between two equal and parallel chords is 24 . find the length if chords ​

Answer 1

Answer:

, AB = 20cm and OC = 24cm

Now,

AC=CB=

2

AB

=10cm (perpendicular drawn from centre of the circle to the chord,bisects the chord)

Then using Pythagorean Theorem:

OA=

(AC 2 +OC 2 )

= (10 2 +24 2 )

=

$\sqrt{676}$

=26

Answer 2

Answer:

26

Explanation:

AB = 20cm

AC = CB = 2

AB = 10cm

OA =(AC^+OC^)

=(10^+24^)

=√676

=26 is answer
