    val radius = 3.0
    val PI = 3.14

    val area = PI * radius * radius
    println("Area = %.2f".format(area))

    val diameter = 2 * radius
    println("Diameter = %.2f".format(diameter))

    val circumference = 2 * PI * radius
    println("Circumference = %.2f".format(circumference))
}



/*
