# Sector Area Calculator

A sector of a circle is a region enclosed by two radii of the circle and the corresponding arc between those radii. In simple terms, it is like a slice or a piece of the circle. The boundaries of the sector are defined by two radii (line segments from the center of the circle to a point on the circumference) and an arc (a portion of the circle's circumference).

Area of a sector means the region within the sector, which is the portion of the circle enclosed by the two radii and the arc. The area of the sector can be calculated using the formula: (θ/360) * π * r^2

Here, (θ/360) represents the fraction of a circle which is then multiplied by area of full circle (i.e πr²) to get the required area.
