(half of circle = half of area) Quarter-Circle (1/4 of circle = 1/4 of area)Any Sector (fractional part of the area)where n is the number of degrees in the central angle of the sector.where C S is the arc length of the sector.Notice that when finding the area of a sector,...
Segment in a Circle:The area enclosed by the chord and the corresponding arc in a circle is called a segment. There are two types of segments – minor segment, and major segment. Sector of a Circle:The sector of a circle is defined as the area enclosed by two radii and the correspondin...
The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. The diameter is twice the radius or d = 2·r. The Greek letter π π represents the number Pi which is defined as the ratio of the circumference of...
Thearea of sectorof a circle is the space enclosed within the boundary of the sector. A sector always originates from the center of the circle. Let us learn more about thearea of sector formula, andhow to find the area of a sector in radiansand degrees. ...
Suppose, instead of the radius we are given the diameter of a circle, how do we calculate the area? We know that in a circle, the radius is half of the diameter. Mathematically, r = $\frac{d}{2}$, where ‘d’ is the diameter and ‘r’ is the radius. ...
into two equal parts. However, if the chord is not the circumference of the circle, it divides the area into two unequal parts. A chord is placed at the centre of the circle, which is the Major Segment. A chord placed at the minor region of the circle is called a Minor Segment. ...
If the points A, B, and O are collinear, the segment AB is a diameter and the circle is divided in two regions with equal area. Otherwise, one of the circular sectors will have smaller area and, for that reason, is going to be called the minor sector. The other, as expected, is ...
Segment area of a circle calculator: It's a "cut-off" part of a circle, limited by a chord or a secant. Central angle calculator: It's an angle with the vertex in the center, whose arms extend to the circumference. Semicircle area calculator. How to use the area of a circle calcula...
The segment of a circle is the region between the chord and arc connecting the endpoints of the chord. A chord is a line segment that connects any two points on a circle. The segment would be the portion cut off of a sector if you sliced it at the point where the radius meets the ...
