Segment Area Calculator: Calculate Circular Segment Area Instantly

Calculate Segment Area

Enter the radius of the circle.
Enter the central angle value.

Welcome to the Segment Area Calculator! Easily determine the area of a circular segment using its radius and central angle. This tool is perfect for students, engineers, and designers working with geometric shapes. Simply input your values to get an accurate result.

Formula:

The formula to calculate the area of a circular segment is:

A = ½ × r² × (θ - sin(θ))

  • A: Area of the circular segment
  • r: Radius of the circle
  • θ: Central angle of the segment (in radians)

If your angle is in degrees, it will be converted to radians internally for the calculation.
