By Mary Smith. Updated: September 2, 2021

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:
1

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’.

2

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.
