从键盘输入圆球半径r(实型)。回车后，输出圆球的体积(保留2位小数)。代码实现如下：includedefinePI3.1415926main(){doublev,r;scanf("%lf",&r);//输入半径。v=(4.0/3)*PI*(r*r*r);printf("%.2lf...

计算表面积和体积，均依赖球体半径。所以需要先输入球体半径，然后根据公式计算出球体表面积和体积。最终输出。3代码：include<stdio.h>intmain(){doubler,v,s;#definePI3.1415927//定义π值，根据需要确定精度。

根据数学公式，球体体积与半径的关系为V=4/3πR^3于是代码思路如下：1输入半径；2计算体积；3输出。代码：define PI 3.1415927int main(){    double r,v...

//计算圆球表面积sqvq=3.0/4.0*pi*r*r*r;//计算圆球体积vqprintf("圆球表面积为:sq=%6.2f\n",sq);printf("圆球体积为:v=%6.2f\n",vq);return0;}...

include<stdio.h>definePI3.141593voidmain(){doubler,v;printf("请输入半径：");scanf("%d",&r);v=4/3*PI*r*r*rprintf("半径为%d的球的体积为：%d",r,v);}...

include<stdio.h>intmain(){doublev,r,pi;pi=3.141592scanf("%lf",&r);v=4.0/3.0*pi*r*r*r;printf("%lf\n",v);return0;}

intmain(void){intr;floatvolume=4.0f/3.0f*3.14*r*r*r;printf("输入球体半径：");scanf("%f",&r);printf("球体体积:%f\n",volume);return0;}...

intmain(void){floats,d;while(scanf("%f",&d)!=EOF){s=4*d*d*d*PI/3;printf("%.3lf\n",s);}return0;}或:intisPrime(unsignedlongn){if(n<=3){returnn>1;}elseif...

\n");scanf("%f",&R);printf("半径为%0.2f的圆的周长是%0.2f,面积是%0.2f\n",R,fun_perimeter(R),fun_area(R));printf("半径为%0.2f的球体体积是%0.2f\n",R,fun_volume(R));return0;}...

答案：代码：include<stdio.h>include<stdlib.h>doubleGV(doublex);intmain(){doublev,r;printf("请输入球半径r：\n");scanf("%lf",&r);v=GV(r);printf("球体的体积：%lf\n",v);system("
