from math import sqrt,ceil,gcd,log;re=lambda:map(int,input().strip().split())
while True:

就那样嘿嘿👀️ ❤️ 👀️ 那个下面printf里面是4乘PI×a的三次方÷3

#include <stdio.h>

#define PI 3.1415926

int main()

{

double a;

while(scanf("%lf",&a)!=EOF){

printf("%.0lf\n",4PIaaa/3);

}

return 0;

}

#include<stdio.h> #include<math.h> int main(){ double m; while(scanf("%lf",&m)!=EOF) { double v=4.0/3.03.1415926pow(3,m); int r = v+0.5; printf("%d\n",r); }

return 0;

}
