Question

用C语言计算一个球的体积,球的体积计算公式为:V=4/3π3.其中r是球的半径,π是圆周率,V是球的体积

Answer 1

#include <stdio.h>
int main()
{
double v,r,pi;
pi=3.141592
scanf("%lf",&r);
v=4.0/3.0*pi*r*r*r;
printf("%lf\n",v);
return 0;
}

Answer 2

是v=4/3π3v=4/3*3.14*（2.45*1/2）的3次方知道了嘛？

Answer 3

#include<stdio.h>
#include<math.h>
int main()
{
double r;
while(scanf("%lf",&r),1)
{
printf("%.3f\n",acos(-1)*r*r*r*4.0/3);
}
return 0;
}

Answer 4

#include <stdio.h>
#define pi 3.141592
void main()
{
double V,r;
printf("please enter r:\n");
scanf("%lf",&r);
V=4/3*pi*r*r*r;
printf("r=%lf\nV=%lf\n",r,V);
}
