Understanding Sector Area
A sector of a circle is a pie-shaped portion enclosed by two radii and an arc. The area of a sector is a fraction of the total area of the circle, determined by the central angle.
The formula to calculate the area of a sector when the central angle (θ) is in degrees and the radius is r is:
If the central angle is given in radians (θ), the formula becomes:
This calculator simplifies the process of finding the sector area, whether you are working on geometry problems, architectural designs, or any application requiring circle sector calculations.
