elsya ryenna you can use maths library like this way and use value of PI by this "Math.PI" import java.util.Scanner; public class Program { public static void main(String[] args) { Scanner sc= new Scanner (System.in); double Area, Radius; System.out.println("Enter value of radius: "); Radius= sc.nextDouble(); Area= (4/3)*Math.PI*(Radius*Radius*Radius); System.out.println("The area with radio " + Radius+ " is: " + Area); } }

example above is wrong because ( 4/3) as int type return 0 correct way is (4.0/3.0) double volume= (4.0/3.0)*Math.PI*(Radius*Radius*Radius);
