Question

A Chord of of length 8cm is drawn at a
distance
of 3cm
from the centre of
the circle
Then radius
from the centre
is
​

Answer 1

Answer:

We know, that the perpendicular to a chord, from the centre of a circle, bisects the chord. Hence, radius of the circle is 5 cm.

Answer 2

Answer:

Radius=5cm

Step-by-step explanation:

Let radius be AB and the centre be A and chord be DB

Perpendicular drawn from center of the circle on the chord bisects the chord

EB=1/2*DB

EB=4 cm

In right angled triangle AEB,

(AB) ^2=EB^2+AE^2

(AB)^2=16+9

(AB)^2=25

AB=5cm
