这条回答哪里出问题了吗？我运行都是正常正确的，为什么不通过？？

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String s1 = sc.next();
        String s2 = sc.next();
        int h,r;
        h = Integer.parseInt(s1);
        r = Integer.parseInt(s2);
        double v = 3.14*r*r*h/1000;
        int t = (int) (20%v==0 ? 20%v : 20%v+1);
        System.out.println(t);

    }
}
