Important Questions from Circles

A circle has diameter 16 cm. A chord in the same circle measures 20 cm. What can be said about this chord?

Show answer

It is impossible because it is longer than the diameter

1. The diameter is the longest chord. 2. The diameter here is 16 cm. 3. A chord of 20 cm is longer than 16 cm. 4. So such a chord cannot be drawn.

The distance of point P from the centre of a circle is 18 cm. The radius is 12 cm. Where does point P lie?

Show answer

In the exterior

1. A point in the exterior has distance from the centre greater than the radius. 2. Here, OP = 18 cm and radius = 12 cm. 3. Since 18 > 12, point P lies in the exterior.

The distance of point Q from the centre of a circle is 12 cm. The radius is 12 cm. Where does point Q lie?

Show answer

On the circumference

1. A point lies on the circumference when its distance from the centre is equal to the radius. 2. Here, OQ = 12 cm and radius = 12 cm. 3. Since the two are equal, Q lies on the circumference.

The distance of point R from the centre of a circle is 9 cm. The radius is 12 cm. Where does point R lie?

Show answer

In the interior

1. A point in the interior has distance from the centre less than the radius. 2. Here, OR = 9 cm and radius = 12 cm. 3. Since 9 < 12, point R lies in the interior.
