# Circumference of a Circle – Definition and Formula

## Circumference of a Circle

A circle is a plane figure formed by a set of points equidistant from a common point. The distance from any point on the circle to the center is called the radius. The circumference of a circle is the distance around the circle. It is measured in units of length, such as inches, feet, or meters.

## Circumference of a Circle – Definition

, Formula

A circle is a closed curve formed by a set of points all of the same distance from a fixed point called the center. The distance from a point on the circle to the center is called the radius. The circumference of a circle is the distance around the circle. The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.

## The Formula for Circumference of the Circle

A circle is a plane figure bounded by a curved line, the circumference, every point of which is equally distant from a point within the figure called the center. The radius is a line segment from the center to any point on the circumference.

The circumference of a circle is π times the diameter. The diameter is the length of a line segment that passes through the center of a circle and is bisected by its circumference.

We can use the formula for circumference of a

## Area of a Circle

A circle is a simple closed curve formed by a set of points equidistant from a given point, the center. The area of a circle is the product of the radius squared and pi (3.14159…).

A = pi*r^2

For example, if the radius of a circle is 3, the area of the circle is 9.42.
