Easily calculate the area of a segment of a circle using our free online calculator. Simply input the radius and the central angle to find the precise area, perfect for geometry problems and engineering applications. Simplify complex calculations instantly!
Formula:
The formula to calculate the area of a segment of a circle is:
A = r² × (θrad - sin(θrad))
- A: Area of the circular segment
- r: Radius of the circle
- θrad: Central angle in radians (if given in degrees, convert using θrad = θdeg × π/180)
- sin(θrad): Sine of the central angle in radians
