Find The Circumference Of A Circle With Our Easy Guide Using The 2Πr Formula

Circumference

The distance around a circle.

Circumference refers to the distance around the edge of a circle or circular object. It is calculated using the formula:

Circumference = 2πr

Where:
– π (pi) is a mathematical constant that represents the ratio of a circle’s circumference to its diameter. It is approximately equal to 3.14159.
– r is the radius of the circle, which is the distance from the center of the circle to any point on its edge.

To use the formula, simply substitute the value of the radius in place of r and use an appropriate value of pi. If the diameter is known, it can be used instead of the radius by dividing it by 2, since the radius is half of the diameter.

For example, if you had a circle with a radius of 5cm, the circumference would be:

Circumference = 2π(5)
Circumference = 10π
Circumference ≈ 31.42cm

Therefore, the circumference of the circle with a 5cm radius is approximately 31.42cm.
