C的话这样就可以了：
#include "stdio.h"
int main(void){
double r=1.5,h=3;
printf("The perimeter is %.2f
",2*3.1415926*r);
printf("The area is %.2f
",3.1415926*r*r);
printf("The volume is %.2f
",3.1415926*r*r*r);
return 0;
}追问用scanf输入数据追答#include "stdio.h"int main(void){ double r,h;
printf("Input r & h(R:)...
");
scanf("%lf%lf",&r,&h);
printf("The perimeter is %.2f
",2*3.1415926*r);
printf("The area is %.2f
",3.1415926*r*r);
printf("The volume is %.2f
",3.1415926*r*r*r);
return 0;
}
#include "stdio.h"
int main(void){
double r=1.5,h=3;
printf("The perimeter is %.2f
",2*3.1415926*r);
printf("The area is %.2f
",3.1415926*r*r);
printf("The volume is %.2f

return 0;

return 0;
}
