A sector is formed by an arc and two of a circle’s radii. Together, these two radii plus the segment’s chord form a triangle. Thus, the area of a circle segment is determined by subtracting the triangle’s area from the sector’s area. A segment of a circle is the region enclosed by the circle’s arc and chord. When something is divided into segments, each segment is called a segment. Similarly, a segment is a component of a circle. However, a segment is not just any section of a circle; it is a specific part of a circle that is sliced by one of its chords.
Area of a circle
The formula for the area of a circle is useful for calculating the area occupied by a circular field or plot. If we have a circular table, the area formula will tell us how much fabric is required to completely cover it. Additionally, the area formula will assist us in determining the boundary length, or the circumference of the circle. Is there volume in a circle? No, a circle lacks volume. A circle is a flat, two-dimensional shape; it lacks volume. A circle has only two dimensions: its area and its perimeter/circumference.
A segment of a circle
A chord divides a circle into two sections, referred to as the circle’s segments. The circle’s two portions are referred to as the minor and major segments, respectively. The region enclosed by the chord is referred to as the minor segment, and the chord intersects the minor arc. In a nutshell, the minor segment is the one with the smallest area. The region enclosed by the chord is referred to as the major segment, and the chord intersects the major arc. In a nutshell, the segment with the greatest area is the key segment. Angles are equal within the same section of a circle.
A circle segment is a region enclosed by a chord and an arc of the circle. Let us define a circle’s chord and arc.
A chord is a line segment that connects any two locations on the circle’s circumference. An arc is a segment of a circle’s perimeter (circumference).
Segments are classified into two categories. There are two segments: a major portion and a minor segment. A major arc forms a major segment of the circle, whereas a minor arc forms a minor segment.
Arcs of circle
Minor arcs and small sectors are always produced by acute centre angles. When the angle created by the two radii is 90 degrees, the sector is referred to as a quadrant (because the total circle comprises four quadrants or fourths). When the two radii intersect to form a 180°, or half of the circle, the sector is referred to as a semicircle and has a main arc. Unlike triangles, sectors do not have line segments defining their bounds. True, the central angle is formed by two radii, but the section of the circumference that forms the third “side” is curved, making calculating the area of the sector a little trickier than calculating the area of a triangle. The arc length is the distance along that curved “side.”
Theorem on a segment of a circle
The alternate segment theorem asserts that the angle formed by a chord and a tangent via either of the chord’s endpoints is equal to the angle formed by the alternate segment in a circle.
Properties of a segment of a circle
It is the region contained within a chord and an arc.
The angle subtended by the circle’s central segment is identical to the angle subtended by the corresponding arc. This angle is frequently referred to as the central angle.
A minor segment is formed by subtracting the equivalent major segment from the circle’s overall area. A major segment is formed by subtracting the equivalent minor segment from the circle’s overall area. A semicircle is the greatest segment of a circle produced by the diameter and the arc that corresponds to it.
Conclusion
The area of a circle segment is determined by subtracting the triangle’s area from the sector’s area. A chord divides a circle into two sections – the minor and major segments. The region enclosed by the chord is referred to as the minor segment, and the chord intersects the minor arc. A circle segment is a region enclosed by a chord and an arc of the circle. There are two categories of segments: a major portion and a minor segment. The area enclosed by the chord is referred to as the major segment, and the chord intersects the major arc. Angles are equal within the same section of a circle. A major arc forms a major segment; a minor segment is formed by subtracting the equivalent major segment from the circle’s overall area.
