C++ program to calculate circle circumference
Following program shows you how to calculate circle circumference.
In this program we get circle radius from user and calculate circumference using following formula
Circumference = 2 X PI X r
#include <iostream>
#include <math.h>
int main() {
float circleRadius;
std::cout << "Please enter the radius of circle:";
std::cin >> circleRadius;
float circumferenceOfCircle = 2 * 3.14 * circleRadius;
std::cout << "Circumference of circle is: " << circumferenceOfCircle;
}
Output:
Please enter the radius of circle: 8
Circumference of circle is: 50.24
