A circle is a simple closed shape in Euclidean geometry. It is the set of all points
in a plane that ... by two concentric circles. Arc: any connected part of the circle.
A pictorial index to the parts of a circle. A diagram with links to full definitions.
Radius, diameter, center, and circumference--all are parts of a circle. Let's go
through each and understand how they are defined.
Parts of a Circle: The radius of the circle is a straight line drawn from the center to
the boundary line or the circumference. The plural of the word radius is radii.
Definitions and formulas for the radius of a circle, the diameter of a circle, the
