Circumference Calculator
Being a geometrical mathematics student, you may have seen that most problems are related to a circle. It is because this geometrical figure has multiple related terms. One of the main terms used for a circle is the circumference. It won’t be an easy task to find this measure if you don’t know how to do so.
Whether you want to make this calculation easier or learn about it, you should use the circumference calculator. It is an advanced maths calculator that has been designed for this particular calculation. You only have to learn the way to use this online tool to find the circumference of any circle.

What is circumference?
The circumference of a circle is the linear distance covered by its edges. In simple words, if we cut the circle into small patches of straight lines, the circumference will be the addition of all those patches. We can understand by comparing it with a perimeter of a specific geometrical figure (polygon).
What is the formula for circumference?
As we know, every point in the circle is equidistant from a fixed point we call its center. The distance from the center to any point is equal to the radius. So, we can use the formula for the circumference based on this particular length i.e. radius. Here is the formula that you can use for finding the circumference of any circle.
Circumference = 2𝝿r
How to find the circumference?
Finding the circumference of a circle won’t take much time and effort. Just put the value of a radius and multiply it with the constants to find the circumference. Let us share an example here.
Example 1:
Find the circumference of a circle if its radius is 5 cm.
Solution:
As we know,
Circumference = 2𝝿r
So,
= 2(3.14) (5) cm
Circumference = 31.42 cm

How to find the circumference of a circle?
To find the circumference of a circle, we only have to put the values in the following formula:
Circumference = 2𝝿r
What is the circumference of a circle?
The circumference of a circle is the linear distance of its edges
What are the rules of circumference?
There is only one rule to find the circumference of a circle which is to multiply the radius with a constant number “Pi” and “2”.
What is a fact about circumference?
The circumference of a circle can be considered the perimeter of the circle because it is also found by combining all patches of its linear distance.
What are the properties of circumference?
How do I find the diameter from the circumference?
As we know, the diameter of a circle is double its radius. So, we can find the diameter of a circle using the following formula:
Diameter = Circumference / 𝝿
- Every point on the circumference of a circle is equidistant from its center.
- The distance between a point on the circumference to the center of the circle is called its radius.
- A circle will always have the same circumference-to-circle ratio.
How do I find the diameter from the circumference?
