circumference
The circumference refers to the distance around the edge or boundary of a closed curved shape, such as a circle
The circumference refers to the distance around the edge or boundary of a closed curved shape, such as a circle. It can be thought of as the perimeter of the circle. It is calculated by using the formula:
Circumference = 2 * π * r
where π (pi) is a mathematical constant approximately equal to 3.14159 and r is the radius of the circle. The radius is the distance from the center of the circle to any point on its boundary.
In other words, the circumference is the length of a string that you would need in order to wrap it exactly once around the edge of the circle.
For example, if you have a circle with a radius of 5 units, the circumference would be:
Circumference = 2 * π * 5 ≈ 31.42 units
It is important to note that the circumference is always proportional to the radius of the circle. If you double the radius, the circumference will also double. Similarly, if you halve the radius, the circumference will also be halved. This relationship is a fundamental property of circles.
