How many parts are there in a circle?
Radius, diameter, center, and circumference–
all are parts of a circle. Let's go through each and understand how they are defined.
What is the main part of the circle?
The
diameter
cuts the circle exactly in half and goes through the centre. The radius is half the length of the diameter and is joined to the centre at one end. A chord is a straight line inside the circle that touches the circumference at 2 points but does not touch the centre of a circle.

How do you identify a circle?
A circle is the set of
all points at a specific distance from a given point in two dimensions
. Two or more circles that have the same center, but different radii. Two or more circles with the same radius, but different centers. Diameter is the measure of the distance across the center of a circle.
How do we name a circle?
A circle is named by its center
. Thus, the circle to the right is called circle A since its center is at point A. Some real world examples of a circle are a wheel, a dinner plate and (the surface of) a coin. The distance across a circle through the center is called the diameter.
