Hi Friend,

Try the following code:

import java.util.*;
class CalculateCyliderVolume
{
    public static void main(String[] args) 
    {   
        double PI=3.14;
        Scanner input=new Scanner(System.in);
        System.out.print("Enter Radius: ");
        double r=input.nextDouble();

        System.out.print("Enter Height: ");
        double h=input.nextDouble();

        double volume=PI*r*r*h;
        System.out.println("Volume of Cylinder: "+volume);
        }
}

Thanks
