Given side of a Decagon, the task is to find out the Perimeter of the Decagon.
Explanation : In geometry, a decagon is a ten-sided polygon or 10-gon. A regular decagon has all sides of equal length and each internal angle will always be equal to 144 degrees.
Examples:
Input : S = 5 Output : The Perimeter of Decagon is : 50 Input : S = 8 Output : The Perimeter of Decagon is : 80
The formula for finding the Perimeter of the Decagon is:
Perimeter = 10 * S where "S" is the side of the Decagon
Below is the program to find perimeter of decagon:
C++
// C++ program to Calculate the Perimeter of a Decagon #include <iostream> using namespace std; // Function for finding the perimeter void CalPeri() { int s = 5, Perimeter; Perimeter = 10 * s; cout << "The Perimeter of Decagon is : " << Perimeter; } // Driver code int main() { CalPeri(); return 0; } |
C
// C program to Calculate the Perimeter of a Decagon #include <stdio.h> // Function for finding the perimeter void CalPeri() { int s = 5, Perimeter; Perimeter = 10 * s; printf ( "The Perimeter of Decagon is : %d" , Perimeter); } // Driver code int main() { CalPeri(); return 0; } |
Java
/*package whatever //do not write package name here */ // Java program to Calculate the Perimeter of a Decagon import java.io.*; class GFG { // Function for finding the perimeter static void CalPeri() { int S = 5 , Perimeter; Perimeter = 10 * S; System.out.println( "The Perimeter of Decagon is : " + Perimeter); } // Driver code public static void main (String[] args) { CalPeri(); } } //This Code is contributed by ajit |
Python3
# Python3 program to Calculate # the Perimeter of a Decagon # Function for finding the # perimeter def CalPeri(): s = 5 Perimeter = 10 * s print ( "The Perimeter of Decagon is : " , Perimeter) # Driver code if __name__ = = '__main__' : CalPeri(); # This code is contributed by # Surendra_Gangwar |
C#
// C# program to Calculate the // Perimeter of a Decagon using System; class GFG { // Function for finding the perimeter static void CalPeri() { int S = 5, Perimeter; Perimeter = 10 * S; Console.WriteLine( "The Perimeter of " + "Decagon is : " + Perimeter); } // Driver code public static void Main () { CalPeri(); } } // This Code is contributed // by anuj_67 |
PHP
<?php // PHP program to Calculate the Perimeter of a Decagon function CalPeri( $s ) { $Perimeter = 10 * $s ; echo "The Perimeter of Decagon is : $Perimeter" ; } // Driver Code $s = 5; CalPeri( $s ); ?> |
Javascript
<script> // JavaScript program to Calculate the Perimeter of a Decagon // Function for finding the perimeter function CalPeri() { var S = 5, Perimeter; Perimeter = 10 * S; document.write( "The Perimeter of Decagon is : " + Perimeter); } // Driver code CalPeri(); // This code contributed by gauravrajput1 </script> |
Output:
The Perimeter of Decagon is : 50
Time Complexity: O(1)
Auxiliary Space: O(1)
