How This Converter Works
Calculates sector area from a positive radius and central angle between zero and one full turn inclusive. The angle can be degrees, radians, gradians, or turns. Area is measured in squared radius units. Blank fields clear output; invalid range or non-finite values show Invalid input; output has six decimals.
Formula or rule
sectorArea = radius^2 * angleRadians / 2
Example
- Input
- Radius 2; angle 90 degrees
- Calculation
- 2^2 * (90 * pi / 180) / 2
- Result
- 3.141593 squared radius units
