Calculate the area of a sector using our easy calculator, plus learn the sector area formulas using central angles in degrees or radians.
In a circle with radius r and centre at O, let ∠AOB = θ (in degrees) be the angle of the sector. Then, the area of a sector of circle formula is calculated using the unitary method. For the given angle the area of a sector is represented by: The angle of the sector is 360°, area of the sector, i.e. the Whole circle = π·r². When the Angle ...
30 kwi 2024 · Calculation Formula. The area \(A\) of a sector of a circle with radius \(r\) and central angle \(θ\) (in degrees) is given by: \[ A = \frac{1}{2}r^2θ_{\text{radians}} \] To convert \(θ\) from degrees to radians, use the conversion factor: \[ θ_{\text{radians}} = θ \times \left(\frac{\pi}{180}\right) \] Example Calculation
Circle Sector Area Formula. The formula for finding the area of a circle sector is: S = \pi *R^2* \dfrac {\alpha^o} {360^o} S = π ∗ R2 ∗ 360oαo. Where S is the area, α is the central angle of the sector in degrees, π is pi (3.14), and R is the radius of the circle.
