Question

Draw any circle and mark a point in its interior.

Answer 1

Hint: First of all just draw a circle. And inside the boundaries of a circle we will find a space then mark a point inside that space of a circle. We can mark a point anywhere inside the circle.

Complete step-by-step answer:
To proceed any further in a question we first need to draw a circle.

In the above circle we can see the two blank spaces with respect to the circle, one blank space lies inside the boundary of a circle and the other blank space lies outside the boundary of a circle. In the below figure, we have shaded the interior region of a circle for a better visualization.

In the above figure, we can see the shaded region. The shaded region is the interior region of the circle (or in other words the shaded region is the area inside the boundary of a circle). Now, we know that any surface or area is an array of points so in the shaded region there are an infinite set of points. To mark a point in the interior of the circle is to mark a point anywhere in the shaded region.
In the below figure, we have marked a point in the interior of the circle.

Note: There are two terms we can say with respect to a circle. One is interior and other is exterior. Interior means area which is inside the boundary of a circle and exterior means area which is outside the circle. So, in some other question if we have asked to mark a point exterior to a circle then mark a point anywhere outside the circle.
