解题思路

没啥好说的

代码实现

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        double h = sc.nextDouble();  //半径
        double r = sc.nextDouble();
        double v;
        int cup;
        v = 3.14*h*r*r;
        cup = (int)(10000/v);
        if(10000%v == 0){
            System.out.printf("%d",cup);
        }
        else{
            System.out.printf("%d",cup+1);
        }

    }
}
