Java Program to Find Volume of Cone

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
