Circumference in math definition
WebFeb 9, 2024 · r, or the circle's radius, is the length of a line that joins the center point with any point lying on the circle. You can find it with the following formulas: If you know the diameter of the circle: r = d / 2. If diameter and area are unknown: r = c / 2π. If diameter and circumference are unknown: r = √ (a / π) WebThe definition of the sector of a circle in geometry can be given as the part of the circle enclosed by two radii and an arc of the circle. The arc of the circle is a part of the boundary/circumference of the circle.
