Question

6. Achord of length 12 cm of a circle is at the distance of 8 am from
its Centre what is the radius of the circle?​

Answer 1

Answer:

GIVEN : Length of chord = 12 cm , Distance of chord from centre = 8 cm.

TO FIND: Radius of circle.

SOLUTION:

A perpendicular from centre to a chord bisects the chord,

So , half chord = 6 cm

Using Pythagoras theorem,

r = root ( 36 + 64)

r = root (100)

r = 10 cm

HENCE, Radius of circle is 10 cm.
