C語言編程 幫忙編個求體積面積的小程序

#define PI 3.14

main()

{

float r,h,l,s1,s2,v1,v2;

printf("%s","please input the radius and high");

scanf("%f %f",&r,&h);

l=2*PI*r;

s1=PI*r*r;

s2=4*PI*r*r;

v1=4*PI*r*r*r/3;

v2=PI*r*r*h;

printf("%d%d",r,h);

printf("circumference is:%5.2f\n",l);

printf("area of the circle is:%5.2f\n",s1);

printf("ball size is:%5.2f\n",s2);

printf("ball volume is :%5.2f\n",v1);

printf("cylindrical volume is :%5.2f\n",v2);

getch();

}輸入數據的時候壹定要用實數類型,用空格分開.
