**The Program in C++ to Print the Area of a Hexagon is given below:**

```
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
float ar,s;
cout<< "Hello Codeauri Family, Please enter side of hexagon :\n";
cin>> s;
ar= (6*(s*s))/(4*tan(M_PI/6));
cout<<"The area of the hexagon is: "<<ar<<"\n";
}
```

## Output:

Hello Codeauri Family, Please enter side of hexagon :

5

The area of the hexagon is: 64.9519

## Pro-Tips**💡**

This program calculates and displays the area of a hexagon.

The user is prompted to input the length of one side of the hexagon.

The area is then calculated using the formula (6 * s^2) / (4 * tan(pi/6)), where s is the length of one side of the hexagon and pi is a mathematical constant.

The result is displayed using the cout statement.

The math.h library has been included to use tan() function and M_PI is a predefined constant in math.h library which is used to store value of pi.
