// Circle.java
//compute area of a circle
// wont compile because of narrowing conversion

class Circle {
  public static void main (String[] args) {
    int radius = 3, area;  //initialize
    area = radius * radius * 3.14159;
    System.out.println("radius is" + radius);

//change area to double and see how this works
//change radius to double and see how this works
//why is double the appropriate btype for this problem
