C++Server Side ProgrammingProgramming

In this tutorial, we are going to learn how to find the diagonal of a regular pentagon.

We have to find the length of the diagonal of the regular pentagon using the given side. The length of the diagonal of a regular pentagon is 1.22 * s where s is the side of the pentagon.

Example

Let's see the code.

 Live Demo

#include <bits/stdc++.h>
using namespace std;
float pentagonDiagonal(float s) {
   if (s < 0) {
      return -1;
   }
   return 1.22 * s;
}
int main() {
   float s = 7;
   cout << pentagonDiagonal(s) << endl;
   return 0;
}

Output

8.54
