About Area of a Sector
In geometry, a sector of a circle is the region bounded by two radii and the arc subtended by these radii. The area of a sector can be calculated using the formula:
$$Area = {\frac{\theta}{360}} \times \pi r^2$$
where θ is the central angle in degrees and r is the radius.
This calculator simplifies finding the area of a sector, useful in various applications from calculating pizza slices to designing circular gardens. Simply input the radius and the central angle to get the sector's area and a visual representation.
