WebDec 22, 2024 · Area of a sector = ( θ 360 ∘) × π r 2 Where, θ is the sector angle, in degrees, that the arc’s centre subtends. The circle’s radius is r’. For example: If the sector of a circle with radius 5 cm has an angle of 30 ∘, determine its area. Solution: r = 5 cm and θ = 30 ∘ Area of a sector = ( θ 360 ∘) × π r 2 A = ( 30 360) × ( 22 7) × 5 2 = 550 840 WebApr 11, 2024 · LAREDO, Texas – Laredo Sector Border Patrol awarded the Youth of the Month honorees for April during a ceremony at John B.

Area of the Sector: Definition, Formula, Derivation and Examples
WebJun 15, 2024 · Figure 6.10.7. Solution. The area of the segment is the area of the sector minus the area of the isosceles triangle made by the radii. If we split the isosceles triangle in half, each half is a 30-60-90 triangle, where the radius is the hypotenuse. The height of \DeltaABC is 12 and the base is 2 (123–√)=243–√. WebTo calculate the area of a sector of a circle we have to multiply the central angle by the radius squared, and divide it by 2. Area of a sector of a circle = (θ × r 2 )/2 where θ is measured in radians. The formula can also be represented as Sector Area = (θ/360°) × πr 2, where θ is measured in degrees. the pryors
