Question

The length of a chord of a circle of 16.8cm, radius is 9.1cm find its distance from the centre​

Answer 1

Answer:

• Distance from the centre is 3.5 cm.

Step-by-step explanation:

Given :

• The length of a chord of a circle of 16.8 cm, radius is 9.1 cm.

To find :

• The distance of chord from the centre.

By theorem

Now it's Radius,

⟹ AC = 1/2AB

⟹ 1/2 × 16.8

⟹ 8.4 cm.

In ΔOCA,

By Pythagoras theorem

OA^2=AC^2+OC^2 OA

⇒ (9.1)^2=(8.4)^2+d^2(9.1)

⇒ 82.81-70.56=d^2

⇒ 82.81−70.56=d^2

⇒ d^2=12.25

⇒ d=3.5 cm

Hence, distance from the centre. is 3.5 cm.
