Online calculator which will help you to find the area of a sector of a circle through the sector angle in radians.
Area of sector of a circle is a part of the whole plane figure bounded by a circle with a radius (r).
The circle sector is defined by the arc between two points (A) and (B) on the circle and two radii drawn from the ends of the arc of points (A) and (B) to the center of the circle, two radii divide the circle's area into two sectors.
