help me out fir this question..​

Answer 1

Answer:

26 cm

Step-by-step explanation:

OP perpendicular to AB

AB =10cm

by the property that if perpendicular is dropped from centre to the chord then it is perpendicular bisector to chord

so, if AB = 10

so AP=PB = 5cm

if AP = 5cm

& OP = 12 cm ( given)

then by pythagoras theoram

OA²=AP²+OP²

OA²=5²+12²

OA²=25+144

OA²= 169

OA= 13

IR RADIUS =13cm

THEN DIAMETER =26cm
