//Main Function , Entry point of Program
fun main(args: Array<String>) {

    //Input Stream
    val scanner = Scanner(System.`in`)

    //Input Radius
    print("Enter Radius of Sphere : ")
    val radius = scanner.nextDouble()

    //surface Area of Sphere
    val sphereSurfaceArea = 4*Math.PI*radius.pow(2)

    //Print Surface Area
    println("Surface Area of Sphere on radius $radius is :$sphereSurfaceArea")
}
