C语言求圆锥体积的源代码如下:define pi 3.1415/*定义常量pi*/ include<stdio.h> int main(){ float v,r,h;/*用float可以计算小数类型*/ printf("请分别输入圆锥的底r和高h:");scanf("%f %f",&r,&h);v=1.0/3*pi*r*r*h;/*用1.0/3因为整数算术运算有封闭性*/ printf("圆锥体...
int main(){ double r, h; // 圆锥底面半径和高 double s, v; // 圆锥表面积和体积 printf("请输入圆锥底面半径和高(用空格分开):");scanf("%lf %lf", &r, &h);s = PI * r * (r + sqrt(r * r + h * h)); // 计算圆锥表面积 v = PI * r * r * h / ...
include <stdio.h>#define PI 3.1415926main(){double r,h;printf("请输入圆锥底面半径:");scanf("%lf",&r);printf("请输入圆锥高度:");scanf("%lf",&h);printf("该圆锥体积为:%.2lf\n",1.0/3*PI*r*r*h);}
include#includevoidmain(){intr,h,pi;r=2;h=3;pi=3.14;printf("圆周长=%d\n",2*pi*r);printf("圆柱底面积=%d\n",pi*r*r);printf("圆柱体积=%d\n",pi*r*r*h);}
PI不能是INT型,改成FLOAT型
float b=getheight();line=sqrt(a*a+b*b);} float cone::surarea(){ return area()+N*getradius()*line;} float cone::volume(){ return area()*getheight()/3;} void cone::show(){ cout<<"圆锥的表面积为:"<<surarea()<<endl;cout<<"圆锥的体积为:"<<volume()<<endl;} ...
