Circumference of a Circle Formula
The formula for finding the circumference of a circle is given by:
C = 2πr
where C represents the circumference and r represents the radius of the circle
The formula for finding the circumference of a circle is given by:
C = 2πr
where C represents the circumference and r represents the radius of the circle.
In this formula, “2π” represents 2 times pi (π), which is an irrational number approximately equal to 3.14159. The value of π is a mathematical constant that represents the ratio of the circumference of any circle to its diameter.
The formula states that if you know the radius of a circle, you can find its circumference by multiplying the radius by 2π.
It is worth mentioning that if you are given the diameter of the circle instead of the radius, you can first find the radius by dividing the diameter by 2, and then use the formula to calculate the circumference using the radius.
For example, let’s say you have a circle with a radius of 5 units. Using the formula, you would calculate the circumference as follows:
C = 2π(5)
C = 10π
C ≈ 31.4159
Therefore, the circumference of the circle with a radius of 5 units is approximately 31.4159 units.
