Halfcircumference

Halfcircumference refers to half the perimeter of a circle. The perimeter of a circle is known as its circumference, which is calculated using the formula C = 2πr, where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. Therefore, the halfcircumference would be half of this value, or πr. This measurement represents the length of an arc that subtends an angle of 180 degrees at the center of the circle, essentially the length of a semicircle. It is a fundamental concept in geometry and is used in various calculations involving circular shapes, such as determining the length of a curved boundary or the distance traveled along a semicircular path.
