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 )
=
=26
Explanation:
Hoe it helped you please mark me as braniest
Answer:
26
Explanation:
AB = 20cm
AC = CB = 2
AB = 10cm
OA =(AC^+OC^)
=(10^+24^)
=√676
=26 is answer
