## Arc of a Circumference – Formulas and Examples

An arc of a circumference or of a circle is a portion of the circumference. The length of an arc is simply the length of this portion of the circumference. The circumference itself can be considered an arc that goes around the circle. Here, we will learn about the...

## Important Parts of a Circle

A circumference is defined as a two-dimensional figure that has a completely round shape. Circles are characterized by having all their points with the same distance from a fixed point. The fixed point is called the center and the distance from the center to the...

## Elements of a Circle with Diagrams

Circles are round two-dimensional figures. Its main characteristic is that each point on the circumference is located at a constant distance from a fixed point. The constant distance is called the radius and the fixed point is called the center of the circumference....

## General Equations of a Circumference

Circumferences are defined as a set of points that are at a constant distance from a fixed point. The fixed point is called the center, while the constant distance is called the radius. We can define a circumference using three equations depending on whether its...

## Equation of the Circumference Using Three Points

The circumference is defined as the set of points that are equidistant from a fixed point called the center. The constant distance from the center to any point on the circumference is called the radius. It is possible to find the equation of the circumference if we...
