Circumference Definition
The length of the boundary of a Circle is called the Circumference. The word Circumference is composed of two Latin Words Circum and Ferre. The word Circum means, around or about and Ferre means to carry. Hence, the word circumference means to carry around. For understanding, take a bangle and a thread. Put the thread around the circle in a closed manner. Now measure the length of this thread. The length of this thread will give you the measurement of the circumference of the Circle.
The use of thread is good at a beginner’s level but not for the advanced stage. Hence, we need to learn Circumference Formula for calculating the Circumference of the circle. Before learning the Circumference formula we should learn what is a Circle and what are its components.
Circumference Formula
Circumference Formula as the name suggests is the formula for calculating the circumference of a circle and as we know the circumference of a circle is defined as the length of the boundary of the circle. For ease of understanding, Circumference is the perimeter of the circle.
Circumference Formula is given by the product of twice the radius and the constant value π. A circle is a two-dimensional curved figure and a bangle is one of the best examples of the Circle. In this article, we will learn about the Circumference Formula and also learn how to calculate the Circumference of a Circle using Circumference Formula. We will also learn the Circumference Formula for semicircles, spheres, and other 3D objects whose at least one face is circular in nature.
