namespace Ch7Ex1Circle
{
    public class Circle
    {
        private double radius;

        public double Radius
        {
            get
            {
                return radius;
            }
            set
            {
                radius = value;
                if (radius < 0)
                    radius = radius * -1;
            }
        }

        public Circle(double radius)
        {
            this.Radius = radius;
        }

        public double getArea()
        {
            return Math.PI * radius * radius;
        }

        public double getCircumference()

        }
    }
