Enter radius in centimeters and display Circumference

 Absolutely! Here's an example C++ program that calculates the circumference of a circle based on the provided radius:

#include <iostream> using namespace std; const double PI = 3.14159; // Constant for Pi int main() { double radius, circumference; cout << "Enter the radius of the circle: "; cin >> radius; circumference = 2 * PI * radius; // Calculate circumference cout << "The circumference of the circle is: " << circumference << endl; return 0; }

This program prompts the user to enter the radius of the circle, calculates the circumference using the formula 2πR, and then displays the result. The value of Pi is stored in a constant named PI and used in the calculation of the circumference.
