=> Create a namespace called constants that contains the following information.
This namespace will be used by programmers to access the values of the most commonly used constants

It looks like your class is already on namespaces. Good, then you have seen namespaces explained. Use that knowledge.

#include <iostream>

// insert your code here

int main() {
  std::cout << "full circle is " << 2 * constants::pi << " radians\n";
}
