c语言输入圆的半径和圆柱的高,求底面积,体积,表面积

Question

如题所述

Answer 1

#include<stdio.h>
#include<math.h>

int main()
{
double pai = 2*acos(0);
double r,h;
double s1,s2,v;
scanf("%lf %lf",&r,&h);
s1 = pai*r*r;
s2 = 2*s1+pai*2*r*h;
v = s1*h;
printf("底面积：%.2lf 体积： %.2lf 表面积：%.2lf\n",s1,v,s2);
return 0;

}

望采纳！

Answer 2

#include<stdio.h>
#define pi 3.1415926
int main()
{float r,h,s1,s2,v;
scanf("%f%f",&r,&h);
s1=pi*r*r;
v=s1*h;
s2=2*s1+2*pi*r*h;
printf("s1=%f\nv=%f\ns2=%f\n",s1,v,s2);
return 0;
}
