Question

In the adjoining figure O is the centre of circle and diameter AC = 26 cm. If chord AB = 10 cm, then the distance between chord AB and centre O of the circle is :​

Answer 1

ANSWER:

12CM

STEP OF EXPLANATION;

AC=26cm

OA=13cm

AB=10cm

AM=5cm

IN TRIANGLE AMO;

OM²+AM²=OA²

OM²+5²=13²

OM²=169-25

OM²=144

OM=√144

OM=12cm

so,the distance between chord AB and centre O of the circle is : 12cm
