What's wrong with it? Here's my code

[Luvian]

#include<stdio.h>
#define PI 3.14;
int main(void)
{
    float r,h,C1,Sa,Sb,Va,Vb;
    scanf("%.2f%.2f",&r,&h);
    C1=(float)2*PI*r;
    Sa=(float)PI*r*r;
    Sb=(float)4*PI*r*r;
    Va=(float)(4/3)*PI*r*r*r;
    Vb=(float)PI*r*r*h;
    printf("C1=%.2f\n
            Sa=%.2f\n
            Sb=%.2f\n
            Va=%.2f\n
            Vb=%.2f",
            C1,Sa,Sb,Va,Vb);
}

errer:invalid type argument of unary'*' (have float)
I'm so confused about it...

#define PI 3.14;

PI is replaced by the value 3.14; and not by 3.14
