D)20cm
ans: anybdy give correct answer i will mark you as brainlist

Answer 1

Answer:

a. 26 cm

Step-by-step explanation:

Let the point where chord AB meet the line from the centre of circle as C

Then distance AC=1/2 of AB

AC=5 cm

Oc=12 cm

By applying Pythagoras theorem,

OA²=AC²+ OC²

=5²+12²

=25+144

=169

OA=13cm

hence diameter=2*radius OA

so the ams is 26 cm
