How to calculate area of sector of a circle without an angle?
A sector is a portion of a circle that can be defined based on the four points mentioned below: A portion of a circle is covered by two radii and an arc. A circle is divided into two sectors and the divided parts are known as minor sectors and major sectors.
This is the reasoning: A circle has an angle of 2 π and an Area of: πr2. A Sector has an angle of θ instead of 2 π so its Area is : θ 2π × πr2. Which can be simplified to: θ 2 × r2. Area of Sector = θ 2 × r 2 (when θ is in radians) Area of Sector = θ × π 360 × r 2 (when θ is in degrees)
A sector of a circle is a portion of the circle made of its arc and two radii. Learn the complete definition along with formulas for area, perimeter and arc length with examples.
Aug 3, 2023 · The sector of a circle is the part enclosed by two radii and the included arc of a circle. It is represented by the symbol ⌔. Sector of a Circle. Types of Sector in a Circle. There are 2 types of sector: minor and major sector.

The 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. Two radii meet at the center of the circle to form two sectors. Minor sector.
As you can see from the figure above, a sector is a pie-shaped part of a circle. It has two straight sides (the two radius lines), the curved edge defined by the arc , and touches the center of the circle.
