The publication presents online calculators and formulas that can be used to calculate the length of the arc of a circular sector through the radius of the circle and the central angle of the sector (in degrees or radians).
Sector Arc Length Calculation
Instructions for use: enter the known values, then press the button “Calculate”. As a result, the length will be calculated taking into account the specified data.
Recall the arc of a circular sector – this is the area between two points lying on the line of a circle and obtained as a result of the intersection of this circle with two radii that formed a sector of the circle. In the figure below, the sector arc AOB is the part of the circle between the points A и B.
Through the radius of the circle and the angle of the sector in degrees
Note: number πused in the calculator is rounded up to 3,1415926536.
