我这个有问题吗？急，🐔

#include
#include
int main()
{
float h; // cylindrical high
float r; // circle radius
float l; // circumference
float s; // circular area
float sq; // the surface area of a sphere
float v; // sphere volume
float vz; // cylindrical volume
float pi = 3.1415926;
scanf("%f,%f",&r,&h);
printf("circumference:l = %6.2f\n",2rpi);
printf("circular area:s = %6.2f\n",rrpi);
printf("the surface area of a sphere:sq = %6.2f\n",4rrpi);
printf("sphere volume:v = %6.2f\n",rrrpi4/3);
printf("cylindrical volume:vz = %6.2f\n",rrpipi);
return 0;
}

你问的是哪方面的问题？编译问题还是运行结果？
printf("cylindrical volume:vz = %6.2f\n",r * r * pi * pi);
这是算啥？怎么有两个pi相乘
