Incrementing the Radius

Here is (yet another) test applet:

// assume that the drawing area is 200 by 200
public class TestCircle10 extends Applet
{
  Circle circ = new Circle();
  
  public void paint ( Graphics gr )
  { 
    circ.setPosition( 100, 100 );

    int count = 1;
    while ( count <= 10 )
    {
      circ.setRadius( ________________ );
      circ.draw( gr );
      count = count + 1;
    }
  }
}

The loop will execute the loop body ten times. The setRadius() method will be used to change to a new radius each time.
