How to calculate the area, diameter, and circumference of a circle in Scala

Answer 1

object CircleCalculations extends App {
  val radius = 3
  val PI = Math.PI

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

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

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



/*
run:
    
Area = 28.27
Diameter = 6.00
Circumference = 18.85
    
*/
