WebA sector of a circle is a portion or part of a circle that is composed of an arc and its two radii. You can compare the sector of a circle to the shape of a pizza slice. A sector is formed when two radii of the circle meet at both ends of the arc. An arc is simply a portion of the circumference of the circle. Sector of a Circle Definition WebNov 18, 2024 · Using the following formulas, one can determine a sector’s area: Area of a Sector of a Circle = (θ/360º) × πr 2, where θ is the sector angle (in degrees) that the arc at the center subtends and ‘r’ is the circle’s radius. Area of a Sector of Circle = 1/2 × r 2 θ, where, θ is the sector angle subtended by the arc at the center ...
