Answer:
Understanding a Circle
Take a circular paper disc, fold it in half and then unfold it.
The line of the fold that divides the circle into two halves is a diameter of the circle.
In the figure below, XY is a diameter.
Trace the outline of a CD, a round plate or a ring on paper and cut it along its edge to get a circular paper disc.
diameter of circle
Fold the paper disc in another way and you will get another diameter of the circle.
Name it ST as below.
diameter of circle
Measure the lengths of the two diameters.
You will note that XY = ST.
Also, XY and ST meet at point O, which is known as the centre or center of the circle.
Any line drawn from the centre O, to the boundary or edge of the circle is a radius of the circle.
In the figure above, OP is a radius.
OQ is another radius.
Measure the lengths of OP and OQ and you will notice that OP = OQ.
