# 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 use the circumference calculator?

If you don’t want to find this **measure** manually, you can use this online calculator by Calculator’s Bag. It has a simple interface that can be understood by anyone. **Read** the following steps to learn how to use this calculator.

- Write the length of the radius in the given input box
- This calculator will automatically solve the problem and show you a measure of the circumference, diameter, and area of the circle.

### FAQ | Circumference Calculator

**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?**

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
