仿照例1-2编程 输入圆柱体的半径和高 计算并输出圆柱体的体积

你好，代码仅供参考

#include <stdio.h>
#define pi 3.14159265
void main()
{
    float V, r, h;
    printf("Enter two number r, h=?\n");
    scanf("%f %f",&r,&h);
    V = pi*r*r*h;
    printf("V=%lf\n",V);
}

#include <stdio.h>
#include <math.h>
int main()
{
float pi = 3.14;
float radius,high,area,volume;
scanf("%f%f",&radius,&high);
area = 2pipow(radius,2)+2piradiushigh;
volume = pipow(radius,2)*high;
printf("%.3f %.3f",volume,area);
return 0;
}
