Answer»

GIVEN A CIRCLE with center O Radius OA=10 cm CHORD AB=12 cm.

To find the distance OM of the chord from O

OM is PERPENDICULAR to chord AB

As perpendicular from the center Na chord bisect the chord. So AM= AB/2 =6 cm

In right angled triangle AMO

AO² =AM² +OM²

⇒10² =6² +OM²

⇒100=36+OM²

⇒OM² =100−36

⇒OM² =64

OM=8cm
