代码如下：（PS：我用的是VC编译器来编译的，如果是TC之类的C语言编译器，建议去掉我代码里的中文字符）#include<stdio.h>main(){ float pai=3.1415926; float radius; float h=3; float crcumference,area,ballsurfacearea,ballsphere,cylidrical; printf("Please Input the Radius(半径):"); scanf("%f",&radius); crcumference=2*pai*radius; area=radius*radius*pai; ballsurfacearea=4*pai*radius*radius; ballsphere=pai*radius*radius*radius*4/3; cylidrical=area*h; printf("The Crcumference(周长):%.2f\n",crcumference); printf("The Area(圆面积):%.2f\n",area); printf("The Ballsurfacearea(圆球表面积):%.2f\n",ballsurfacearea); printf("The Ballsphere(圆球体积):%.2f\n",ballsphere); printf("The Cylidrical(圆柱体积):%.2f\n",cylidrical);}
