Circle class

i did my program but i m getting many error  in my program. errors like unexpected token ":" or ";" before double and this is my program.

 
#include<iostream>


 using namespace std;

 class Circle
 {
    private
    double PI = 3.14159;
    double radius;

    public Circle()
    {
        radius = 0.0;
    }

    public Circle(double r)
    {
        radius = r;
    }

    public void setRadius(double r)
    {
        radius = r;
    }

    public double getRadius()
    {
        return radius;
    }

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

    public double getDiameter()
    {
        return radius * 2;
    }

    public double getCircumference()
    {
        return 2 * PI * radius;
    }
 };


int main()
 {
     double radius;

     cout << "Enter the circle's radius:" << endl;
     cin >> radius;

     cout << "Radius:" << c.getRadius() << endl;

     cout << "Area:" << c.getArea() << endl;

     cout << "Diameter:" << c.getDiameter() << endl;

     cout << "Circumference:" << c.getCircumference() << endl;

     return 0;
 }
