//	Goal:	This program will solve for the area and circumference of 
//	a circle
//

#include <iostream>

using namespace std;

int main()
{
	// 1. declare variables
	float radius, area, circumference;
	string star_line = "**********************";

	// 2. input - prompt a msg
	cout << star_line;
	cout << "\n\nPlease input the radius of the circle: ";
	cin >> radius;

	// 3. computing
	area = 3.14 * radius * radius;
	circumference = 2 * 3.14 * radius;

	// 4. output
	cout << "The area of the circle is: " << area << endl;
	cout << "The circumference of the circle is: " << circumference << "\n\n\n";
	cout << star_line << endl;

	return 0;
