# What's the Difference Between Circle and Circumference?

*Circle* and *circumference* are two geometrical terms that often get confused and create doubts when you have to use them. Although you might think they are synonyms, they are not. Don't worry: here at oneHOWTO, we'll show you **what is the difference between circle and circumference**.

## Steps to follow:

According to Merriam-Webster's Dictionary, a **circle** is ‘a perfectly round shape: a line that is curved so that its ends meet and every point on the line is the same distance from the center’.

A **circumference**, on the other hand, is ‘the length of a line that goes around something or that makes a circle or other round shape’.

So, **what is the difference between circle and circumference**? When we use the word *circle*, we refer to the familiar round shape. When we say *circumference*, we are speaking of the length of the perimeter line of a circle.

So you can understand, in the image you can see below, **the circumference is the exterior line** which is painted in blue, while the** inner part** which is painted in yellow is the area of the circle.
