Answer 1

Answer:

So the distance of a chord from the centre is 6 cm

Answer 2

Answer:

Let AB be the chord with length =16cm

OA=radius=17cm

Now, OC⊥AB

Then, AC=CB=8cm (perpendicular drawn from the centre of the circle to the chord,bisects the chord)

∴OC=

(OA

−AC

=

(225)

=15cm

Hence, OC=15cm
