Calculateur de Sector Area
Calculate the area of a circular sector from radius and central angle.
Formula and method
This calculator computes Sector area directly in your browser without sending data to an external server.
Mathematical formula
- Sector area:
π × radius × radius × (angleDeg ÷ 360)
Variables and parameters
- Radius (radius): default value 10.
- Central angle (angleDeg): default value 90 deg.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
