Write the following function:

function areaOfPolygonInsideCircle(circleRadius, numberOfSides)

areaOfPolygonInsideCircle :: Double -> Int -> Double
areaOfPolygonInsideCircle circleRadius numberOfSides = undefined

function areaOfPolygonInsideCircle($circleRadius, $numberOfSides)

public static double AreaOfPolygonInsideCircle(double circleRadius, int numberOfSides)

(defn area-of-polygon-inside-circle [circle-radius number-of-sides]

def area_of_inscribed_polygon(circle_radius, number_of_sides):

def area_of_polygon_inside_circle(circle_radius, number_of_sides) do

def area_of_polygon_inside_circle(circle_radius, number_of_sides)

def area_of_polygon_inside_circle(circle_radius, number_of_sides)

static double areaOfPolygonInsideCircle(circleRadius, numberOfSides)

double areaOfPolygonInsideCircle (double circleRadius , int numberOfSides)

areaOfPolygonInsideCircle(_ circleRadius: Double, _ numberOfSides: Int) -> Double

double area_of_polygon_inside_circle(double circle_radius, int number_of_sides);

double area_of_polygon_inside_circle(double circle_radius, int number_of_sides);

double areaOfPolygonInsideCircle(double circleRadius, int numberOfSides)

areaOfPolygonInsideCircle = (circleRadius, numberOfSides)

export function areaOfPolygonInsideCircle(circleRadius: number, numberOfSides: number): number

public static double areaOfPolygonInsideCircle(double circleRadius, int numberOfSides) 

areaOfPolygonInsideCircle = (circleRadius, numberOfSides)

func AreaOfPolygonInsideCircle(circleRadius float64, numberOfSides int) float64

area_of_polygon_inside_circle(circle_radius, number_of_sides)

fn area_of_polygon_inside_circle(circle_radius: f64, number_of_sides: i32) -> f64

It should calculate the area of a regular polygon of numberOfSides, number-of-sides, or number_of_sides sides inside a circle of radius circleRadius, circle-radius, or circle_radius which passes through all the vertices of the polygon (such circle is called circumscribed circle or circumcircle).

The answer should be a number rounded to 3 decimal places.
