# What is the formula of the circumference?

**circle**(Pi multiplied by the diameter of the

**circle**). Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the

**circle**!

Similarly, how do you find the circumference?

**How to find the circumference of a circle:**

- The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle.
- If a circle has a diameter of 4, its circumference is 3.14*4=12.56.
- If you know the radius, the diameter is twice as large.

Secondly, what is circumference from diameter? The distance around the edge of the circle is called the **circumference**. The distance from one side of the circle to the other, going through the center of the circle, is the **diameter**. The constant pi, designated by the Greek letter π, is the ratio of the **circumference** to the **diameter** of a circle.

Also know, what is 2πr?

The circumference formula is used to calculate the distance around a circle. Circumference formulas: C = **2πr** or C = πd. r is the radius and d is the diameter. The diameter is the longest chord that runs through the center of the circle.

What is formula of circumference?

Write down the formula for finding the circumference of a **circle** using the diameter. The formula is simply this: C = πd. In this equation, "C" represents the circumference of the **circle**, and "d" represents its diameter. That is to say, you can find the circumference of a **circle** just by multiplying the diameter by pi.
