The edge of a circle is perfectly round, composed with a set of points that are all the same distance from the centre of the circle. A totally flat disc is an example of a circle.
A circle is a shape with equal distances from the centre to any point of the edge (circumference).
Area of a Circle
|Area (A)||=||π||×||radius squared|
Edge (Circumference) of a Circle
|Edge||=||2 × π × radius|
|Edge||=||2 π r|
