Program to calculate Volume of Cone

Program of calculating the volume of a cone in different Programming languages

Program 1: Write a Program in C language:

// This C program which uses a function to calculate the volume of a cone.  
#include <stdio.h>  
#define pi 3.14  
float find_Volume_of_cone(float r, float h) // It is a function to find volume   
{   
float Volume_of_cone;  
Volume_of_cone= (pi *  r * r * h) / 3 ;   
// It is a formula for calculating a volume of cone   
return (Volume_of_cone);   
}   
float main()   
{   
float r;   
float h;  
printf("Enter the radius of the cone:");   
scanf("%f",&r);  
printf("Enter the height of the cone:");   
scanf("%f",&h);  
float x = find_Volume_of_cone(r,h);  
printf("Volume of the cone is: %f",x);     
return 0;   
}  

Output of Above C program:

Enter the radius of the cone: 5
Enter the height of the cone: 10
Volume of the cone is: 261.666656

Program 2: Write a Program in Java language:

// This a Java program which calculates the volume of a cone.  
class findvolume {   
static float find_Volume_of_cone(float r, float h)   
{   
final float pi = (float) 3.141592653589793;   
float Volume_of_cone;  
Volume_of_cone=  (pi *  r * r * h) / 3 ; // It is a formula for calculating the volume of cone   
return(Volume_of_cone);   
}   
// Driver method   
public static void main(String[] args)   
{   
float radius = 5, h = 10;   
System.out.println("The Volume of a cone in Java:");  
System.out.println(find_Volume_of_cone(radius,h));   
}   
}  

Output of Above Java program:

The Volume of a cone in Java:
261.7994

Program 3: Write a Program in PHP programming language.

<?php   
// This a  PHP program which calculates the volume of a cone.    
// Function to find volume   
function find_Volume_of_cone($r, $h)   
{     
$pi =  3.14;  
$Volume_of_cone =  ($pi *  $r * $r * $h) / 3 ; // It is a formula which calculates the volume  and store the value in the volume_of_cone variable.   
return ($Volume_of_cone);   
}   
  
$radius = 10;   
$height = 10;  
  
echo find_Volume_of_cone($radius, $height);   

Output of Above PHP program:

1046.6666666667

Program 4: Write a Program in Python programming language.

# This is a python program which calculates the volume of a cone.   
# It is a function to calculate the volume of cone  
import math  
pi = math.pi  
  
def find_Volume_of_cone(r,h):  
    return (pi *  r * r * h ) / 3 # It is a formula which calculates the value of volume.   
  
radius = 5  
height = 10  
print(find_Volume_of_cone(radius, height))  

Output of Above Python program:

261.79938779914943
