M L Aggarwal Solutions for Exercise 3: Multiple Choice Questions

If $P\text{ and} Q$ are any two points on a circle, then the line segment $PQ$ is called a:

If $P$ is the point in the interior of a circle with centre $O$ and radius $r$, then

The circumference of a circle must be

$AD$ is diameter of a circle and $AB$ is a chord. If $AD= 34 \mathrm{cm} \text{and} AB= 30 \mathrm{cm}$, then the distance of $AB$ from the centre of circle is

If $AB= 12 \mathrm{cm}, BC= 16 \mathrm{cm}\text{ and} AB$ is perpendicular to $BC$, then the radius of the circle passing through the points $A, B\text{ and} C$ is

In the adjoining figure, $O$ is the centre of the circle. If $OA= 5 \mathrm{cm}, AB= 8 \mathrm{cm} \text{and} OD\perp AB$, then length of $CD$ is equal to:
