             d=Math.PI*r*r;

             break;

case 'S': System.out.println("Enter side");

             double s= sc.nextDouble( );

             d=s*s;

             break;

case 'r': System.out.println("Enter length and breadth");

             d=l*b;

System.out.println("The required area "+d);

}

}
