The publication presents online calculators and formulas that can be used to calculate the area of a circle sector through the radius of the circle and the length of the arc, or the radius and central angle of the sector (in degrees or radians).
Calculation of the area of the circular sector
Instructions for use: enter the known values, then press the button “Calculate”. As a result, the area will be calculated taking into account the specified data.
Recall sector of a circle – it’s part of a circle, which is formed by its two radii and an arc between them. In the figure below, the circular sector is shaded in yellow, and AB – this is his arc.
Through the radius of the circle and the length of the arc of the sector
Note: number πused in the calculator is rounded up to 3,1415926536.
