. In the figure o is the centre of the circle
. om=3cm and AB=8cm. Find the radius of the circle.
Given o is the center of circle, om=3cm and AB=8cm
Join o to A and B
In figure OM show that the perpendicular from center o on cord AB
Perpendicular from the Center of a Circle to a Chord Bisects the Chord.
Then AO is the radius of circle is 5cm.
Hence, the correct option is (a) i.e. 5cm.
