What Perimeter of a Sector Calculator does

The Perimeter of a Sector Calculator determines the total boundary length of a circular sector by combining the arc length and two radial segments. Users input a radius and a central angle to receive the perimeter, with the arc length calculated automatically. The result provides a single measurement that accounts for both the curved edge and the straight sides of the sector, eliminating the need for manual formula application. The tool is designed to handle the geometric complexity of sector boundaries in a single output value.
