Write a Program to find the Perimeter of Ellipse

Program of calculating the perimeter of an ellipse in different Programming languages

Program 1: Write a Program in C language:

// This is a C program which uses a function to find the perimeter of ellipse.  
#include <stdio.h>  
float find_Perimeter_of_ellipse(float a, float b) // It is a C function to find perimeter   
{   
float Perimeter_of_ellipse;  
Perimeter_of_ellipse= 2 * 3.14 * sqrt( ( (a* a) + (b * b) ) / 2 ); // It is a formula for calculating a perimeter of ellipse   
return (Perimeter_of_ellipse);   
}   
float main()   
{   
float a;   
float b;  
printf("Enter the semi-major axis of the ellipse:");   
scanf("%f",&a);  
printf("Enter the semi-minor axis of the ellipse:");   
scanf("%f",&b);  
printf("Perimeter of the ellipse is: %f", find_Perimeter_of_ellipse(a, b));     
return 0;   
}   

Output of Above C program:

Enter the semi-major axis of the ellipse:5
Enter the semi-minor axis of the ellipse:10
Perimeter of the ellipse is: 49.647758

Program 2: Write a Program in Java language:

// This is a program written in Java Languages, which finds the perimeter of the ellipse.  
import java.lang.Math;  
class findperimeter {   
static double find_Perimeter_of_ellipse(float a, float b)   
{    
double Perimeter_of_ellipse;  
Perimeter_of_ellipse = 2 * 3.14 * Math.sqrt( ( (a* a) + (b * b) ) / 2);  
return(Perimeter_of_ellipse);   
}   
// Driver method   
public static void main(String[] args)   
{   
float a= 5, b = 10;   
System.out.println("The Perimeter of a ellipse is:");  
System.out.println(find_Perimeter_of_ellipse(a, b));   
}   
}  

Output of Above Java program:

The Perimeter of a ellipse is:
49.647759264643554

Program 3: Write a Program in PHP programming language.

<?php   
// This a  PHP program which finds the perimeter of a ellipse.    
// Function to find perimeter   
function find_Perimeter_of_ellipse($a, $b)   
{     
$Perimeter_of_ellipse = 2 * 3.14 * sqrt( ( ($a* $a) + ($b * $b) ) / 2 ); // It is a formula which finds the perimeter  and store the value in the perimeter_of_ellipse variable.   
return ($Perimeter_of_ellipse);   
}   
$a = 5;   
$b = 10;  
  
echo find_Perimeter_of_ellipse($a, $b);   
?>  

Output of Above PHP program:

49.647759264644

Program 4: Write a Program in Python programming language.

# This is a python program which finds the perimeter of a ellipse.   
# It is a function to find the perimeter of ellipse  
from math import sqrt  
def find_Perimeter_of_ellipse(a, b):  
    return ( 2 * 3.14 * sqrt( ( (a* a) + (b * b) ) / 2 )) # It is a formula which finds the value of perimeter.   
a = 5  
b= 10  
print(find_Perimeter_of_ellipse(a, b) )  

Output of Above Python program:

49.647759264644
