Explained With Example: Determine the Circumference of a Circle

BY Team Aakash Byju's

Definition: A circle is a two-dimensional object made up of a group of points that are all at the same distance (radius) from a fixed point (center) on the plane.

The length of a circle's boundary is specified as its circumference. It's also known as a circle's perimeter.
