Question

6. A chord of length 20 cm is drawn at a distance of 24 cm from the centre of a circle. Find the radius of the circle.
O 23 cm
O 26 cm
0 24 cm
O 25 cm​

Answer 1

Answer:

b)26 cm

Step-by-step explanation:

Here, AB = 20cm and OC = 24cm

Now,

AC=CB= 2AB =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 ) = 676

=26
