Write a program to find the Area of an Icosahedron

Program of calculating the area of an icosahedron in different Programming languages

Program 1: Write a Program in C language:

// This C program which uses a function to find the area of a icosahedron.  
#include <stdio.h>  
float find_Area_of_icosahedron(float a) // It is a function to find area   
{   
float Area_of_icosahedron;  
Area_of_icosahedron= 5 * sqrt(3) * a * a ; // It is a formula for calculating a area of icosahedron   
return (Area_of_icosahedron);   
}   
float main()   
{   
float side;  
printf("Enter the side of the icosahedron:");   
scanf("%f",&side);  
printf("Area of the icosahedron is: %f", find_Area_of_icosahedron(side));     
return 0;   
}   

Output of Above C program:

Enter the side of the icosahedron:5
Area of the icosahedron is: 216.506348

Program 2: Write a Program in Java language:

// This a  Java program which finds the area of a icosahedron.  
class findarea {   
static float find_Area_of_icosahedron(float a)   
{    
float Area_of_icosahedron;  
Area_of_icosahedron= (float) (5 * Math.sqrt(3) * a * a) ; // It is a formula for calculating the area of icosahedron   
return(Area_of_icosahedron);   
}   
// Driver method   
public static void main(String[] args)   
{   
float side = 3;   
System.out.println("The Area of a icosahedron is:");  
System.out.println(find_Area_of_icosahedron(side));   
}   
}  

Output of Above Java program:

The Area of a icosahedron is:
77.94228

Program 3: Write a Program in PHP programming language.

<?php   
// This a  PHP program which finds the area of a icosahedron.    
// Function to find area   
function find_Area_of_icosahedron($a)   
{     
$Area_of_icosahedron = 5 * sqrt(3) * $a * $a; // It is a formula which finds the area  and store the value in the area_of_icosahedron variable.   
return ($Area_of_icosahedron);   
}   
$side = 2.5;  
echo find_Area_of_icosahedron($side);   
?>  

Output of Above PHP program:

54.13

Program 4: Write a Program in Python programming language.

# This is a python program which finds the area of a icosahedron.   
from math import sqrt  
def find_Area_of_icosahedron(a):  
    return ( 5 * sqrt(3) * a * a ) # It is a formula which finds the value of area.  
# main code begins  
Side = 5  
print(find_Area_of_icosahedron(Side))  

Output of Above Python program:

216.506348
