Semi Circle Circumference Formula
Now one can think that if a semicircle is half of the circle then its circumference or perimeter would also be half of the circle. But that is actually wrong. If we see a semicircle, we see that arc is half of that of a circle but it is also enclosed by a line which is actually the diameter of the circle.
The formula for the circumference or perimeter of the semicircle is given by
Circumference of Semicircle = πr + 2r = 1/2(Circumference of Circle) + Diameter
where, r is the radius of the circle
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.
