Question

two parralel lines touch the circle at points A andB respectively .if area of the circle is 25 py cm^2 ,then find the length of AB

Answer 1

πr^2=25πcm^2
r=5cm
The parallel lines will touch the diameter's endpoints. so, the distance between two parallel lines is equal to diameter.
d=2r=2*5cm=10cm

Answer 2

This is the right answer for this question.
