Question

the radius of the circle is 6 cm .find the perpendicular distance from the centre of the circle to the circle which is 8 cm length
​

Answer 1

Answer:

We will represent the given data in the figure

We know that perpendicular drawn from the centre to the chord divides the chord into two equal parts.

So, AM= MB=AB/2=8/2=4cm

Using Pythagoras theorem in the AMO,

OM²=OA²-AM²

=6²-4²

=36-16

=_/20

=2_/5cm
