find the area of a segment of a circle in swift

To find the area of a segment of a circle, you first need to calculate the area of the sector formed by the segment of the circle. You can then subtract the area of the triangle formed by the radii and the chord from the area of the sector to get the area of the segment.

Here's a function in Swift that takes in the radius of the circle, the angle of the segment in radians, and the length of the chord, and returns the area of the segment:

main.swift
func areaOfSegment(radius: Double, angle: Double, chordLength: Double) -> Double {
    let sectorArea = pow(radius, 2) * angle / 2.0
    let triangleArea = pow(chordLength, 2) / (4.0 * radius) * sin(angle)
    return sectorArea - triangleArea
}

You can call this function with the appropriate values for the radius, angle, and chord length to get the area of the segment. Keep in mind that all angle measures must be in radians.
