Web18 mei 2024 · To calculate the area of a segment bounded by a chord and arc subtended by an angle θ, first work out the area of the triangle, then subtract this from the area of the sector, giving the area of the segment. (see diagrams below) The triangle with angle θ can be bisected giving two right angled triangles with angles θ/2.

Web9 apr. 2024 · Thankfully, this sector of a circle formula would work with any stated fraction of a circle. Even if the known portion is 1/120 of a circle, simply multiply the formula for the area of a circle by 1/120. So, when given the portion of the circle, the sector of a circle formula is: A = (portion of the circle) (π x r2) Web3 nov. 2024 · If the central angle is measured in radians, the formula instead becomes: \text {sector area} = r^2 × \frac {\text {central angle in radians}} {2} sector area = r2 × 2central angle in radians.
