find the volume of a regular polygon inscribed in a cone in swift

main.swift
func volumeOfRegularPolygonInCone(n: Int, r: Float, h: Float) -> Float {
    let π: Float = .pi

    // Step 1 - Determine the number of sides of the regular polygon
    let sides = Float(n)

    // Step 2 - Calculate the length of each side of the polygon
    let a = 2 * r * sin(π / sides)

    // Step 3 - Calculate the slant height of the cone
    let slantHeight = sqrt(pow(r, 2) + pow(h, 2))

    // Step 4 - Calculate the height of the cone
    let height = h

    // Step 5 - Calculate the area of the base of the polygon
    let baseArea = (sides * pow(a, 2)) / (4 * tan(π / sides))

    // Step 6 - Calculate the volume of the polygon
    let volume = (1 / 3) * baseArea * height

    return volume
