Circumference
Distance around a circle,that is, the perimeter of acircle
The circumference is the distance around the outside of a circular object or shape. It is calculated by using the formula C = 2πr, where C represents the circumference, π represents the mathematical constant pi (approximately equal to 3.14), and r represents the radius (the distance from the center of the circle to any point on its circumference).
To find the circumference of a circle, simply multiply the radius by 2π. For example, if the radius of a circle is 5 units, then the circumference would be 2(3.14)(5) = 31.4 units.
The circumference is an important measurement in many real-world applications, such as in calculating the length of wire needed to wrap around a spool or the distance around the edge of a circular table. It is also a key concept in geometry and trigonometry.
