Write a program to find the Area of Tetrahedron

Program of calculating the area of a tetrahedron in different Programming languages

Program 1: Write a Program in C language:

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

Output of Above C program:

Enter the side of the tetrahedron:5
Surface area of the tetrahedron is: 43.301270

Program 2: Write a Program in Java language:

// This a  Java program which finds the area of a tetrahedron.  
class findarea {   
static double find_area_of_tetrahedron(float a)   
{    
double area_of_tetrahedron;  
area_of_tetrahedron= ( Math.sqrt(3) * ( a * a )); // It is a formula for calculating the area of tetrahedron   
return(area_of_tetrahedron);   
}   
  
// Driver method   
public static void main(String[] args)   
{   
float side = 3.9;   
System.out.println("The area of a tetrahedron is:");  
System.out.println(find_area_of_tetrahedron(side));   
}   
}  

Output of Above Java program:

The area of a tetrahedron is:
43.30127018922193

Program 3: Write a Program in PHP programming language.

<?php   
// This a  PHP program which finds the area of a tetrahedron.    
// Function to find area   
function find_area_of_tetrahedron($a)   
{     
$area_of_tetrahedron = ( sqrt(3) * ( $a * $a )); // It is a formula which finds the area and store the value in the area_of_tetrahedron variable.   
return ($area_of_tetrahedron);   
}   
$side = 105;  
echo find_area_of_tetrahedron($side);  

Output of Above PHP program:

19095.860153447

Program 4: Write a Program in Python programming language.

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

Output of Above Python program:

43.301270
