Parts of a circle include the diameter, circumference, radius, and center. The diameter of a circle is a chord passing through the center. The center is a single point at which the distance to locations on the circumference are equal. The circumference is the perimeter of the circle. The radius of the circle is half the diameter, and the distance from the center to a point on the outlying circumference.

Only the diameter can divide the circle in to two equal parts.
Color and parts
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared Radius of a circle = diameter/2 Degrees around a circle = 360 degrees
There are five parts of a circle. They are-1.Radius: It is the parts of the circle that be defined as the distance between the center of the cirlce and a point on the circle.2.Diameter: It is the parts of the circle that be defined as the distance between the two point on the circle which cross through the center of the circle. Note: Every diameter of a circle is a chord; however, not every chord is a diameter. Whether a chord passes through the center determines if it is or is not the diameter.3.Chord: It is the parts of the circle that be defined as the line whose end points are on the circle.4.Secant Line: This line intersects the circle exactly at two points.5.Tangent Line: This line intersects the circle on the point.Thus we can define parts of a circle.
The three parts are:the interior of the circle, the points on the circle (points on its circumference) the outside of the circle.
