Asectoris the area bounded by any two radii and the circle’s edge. How to Find the Radius of a Circle You canfind the radius of a circleusing one of the following formulas. Given the Diameter The radius of a circle is equal to half the circle’s diameter. The following formula defin...
Area of a Sector Formula: If a sector makes an angle θ (measured in radians) at the center, then the area of the sector of a circle = (θ× r2)÷ 2. Here, θ is in radians.Length of Chord Formula: It can be calculated if the angle made by the chord at the center and the ...
The radius of a circle is defined as a line segment that joins the center to the boundary of a circle. The distance from the center point to any endpoint on the circle is called the radius of a circle. Learn about the radius formulas with solved examples
A circle can be defined as, it is the locus of all points equidistant from a central point. In this we discuss about Properties of circle, circle formulas
In this article, we cover the most important properties of circles and important circle formulas such as area and perimeter of a circle.
If radius and diameter are unknown, you can calculate it from the circumference: a = c² / 4π If you are interested in calculations of some fraction of a circle, check: Our dedicated semicircle area calculator to find the area of half a circle; Sector area tool to check the area of...
An arch length is a portion of the circumference of a circle. The ratio of the length of an arc to the circumference is equal to the ratio of the measure of the arc to $360$ degrees. A sector of a circles is the region bounded by two radii of the circle and their intercepted arc...
Circle: Sector The part of a circle enclosed by any two other radii and an arc is called a circle. When a major arc forms a sector, it is called the major sector, and when the sector is formed by a minor arc, it is called the minor sector. ...
A sector of a circle is called the minor sector if the minor arc of the circle is a part of its boundary. A sector is called the major sector if the major arc of the circle is a part of its boundary.Circle FormulasArea of a circle:...
Sectoris a fraction of the area of a circle with a radius on each side and an arc. Segmentis an interior part of a circle bound by a chord and an arc. Tangent (T) - A line that touches a curve at just one point such that it is perpendicular to a radius line of the curve. ...
