In this article we will discuss about how to find volume of cone.

Program to Find Volume of Cone

Before going into the program, let’s see how we find the volume of cone.

Formula for Volume of Cone = pie * (r*r) * h/3

Where,

  • ‘r‘ represents radius of cone.
  • ‘h‘ represents height of cone.

Let’s see different ways to find volume of cone.

The best and excellent way to learn a java programming language is by practicing Simple Java Program Examples as it includes basic to advanced levels of concepts.

Approach:

  1. Take user input or declare the values for height and radius of the cone and store it in double variable say h and r respectively.
  2. Then using the formula find volume of cone and store it in a variable say volume.
  3. Then display the result.

Method-1: Java Program to Find Volume of Cone By Using Static Value

import java.util.*;

public class Main
{  
    public static void main(String args[])  
    {  
        //Scanner class object created
        Scanner s= new Scanner(System.in);
        //radius declared
        double r=3.3;
        //height declared
        double h=6.6; 
    
        //pie value declared
        double pie=3.14285714286;
        
        //calulating volume of cone using formula
        double volume=pie*(r*r)*h/3;  
        
        System.out.println("Volume of cone : "+volume);  
    }  
}
Output:

Volume of cone : 75.29657142863987

Method-2: Java Program to Find Volume of Cone By User Input Value

import java.util.*;

public class Main
{  
    public static void main(String args[])  
    {  
        //Scanner class object created
        Scanner s= new Scanner(System.in);
        //Taking radius input from user
        System.out.println("Enter radius of cone : ");
        double r=s.nextDouble();
        //Taking height input from user
        System.out.println("Enter height of cone : ");
        double h=s.nextDouble(); 
        
        double pie=3.14285714286;
        
        //calulating volume of cone using formula
        double volume=pie*(r*r)*h/3;  
        
        System.out.println("Volume of cone : "+volume);  
    }  
}
Output:

Enter radius of cone : 3.3
Enter height of cone  6.6
Volume of cone : 75.29657142863987

Method-3: Java Program to Find Volume of Cone By User Defined Method

import java.util.*;

public class Main
{  
    public static void main(String args[])  
    {  
        //Scanner class object created
        Scanner s= new Scanner(System.in);
        //Taking radius input from user
        System.out.println("Enter radius of cone : ");
        double r=s.nextDouble();
        //Taking height input from user
        System.out.println("Enter height of cone : ");
        double h=s.nextDouble(); 
        
        //calling the findVolume() method
        findVolume(r,h);
    }
    
    //user defined method
    //findVolume() method to find volume of cone
    public static void findVolume(double r, double h)
    {
        //pie value declared
        double pie=3.14285714286;
        
        //calulating volume of cone using formula
        double volume=pie*(r*r)*h/3;  
        
        System.out.println("Volume of cone : "+volume);  
    }  
}
Output:

Enter radius of cone : 3.3 
Enter height of cone  6.6 
Volume of cone : 75.29657142863987
