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–√. WebFigure 1: Segment of a Circle Derivation. In fig. 1, if ∠AOB = θ (in degrees), then the area of the sector AOBC (A sector AOBC) is given by the formula; (A sector AOBC) = θ/360° × πr 2. Let the area of ΔAOB be A ΔAOB. So, the area of the segment ABC (A segment ABC) is given by. (A segment ABC) = (A sector AOBC) – A ΔAOB.

WebGiven an angle θ measured in degrees, extended to the perimeter of the circle, then the length of the arc subtended by the angle is θ 360 th of the entire circle's circumference: L = θ ∘ 360 ∘ ⋅ 2 π r = 2 π r θ ∘ 360 ∘. Likewise, given a circle O with radius r, the area A of a sector determined by θ (measured in degrees) is θ ...

WebA sector of a circle is a part of a circle enclosed by two radii and an arc between them. We name the sectors based on the type of arc between the radii. If the central angle is less than 1 8 0 ∘ or 𝜋 rad, we refer to this as a minor sector. If the central angle is larger than that, we refer to this as a major sector.
