How to convert this algebraic expression 4/3 pi r^3 to java expression where pi=22/7

Answer 1

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);

}
}

Answer 2

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);
