How to find volume of cylinder and cone using function with arguments?

//Write a program to find volume of cylinder and cone using function with arguments..

int main()

{

    float cyr,cyh,cor,coh;

    void cyv(float cyr,float cyh);

    void cov(float cor,float coh);

    printf("\n enter radius and height of cylinder:");

    scanf("%f%f",&cyr,&cyh);

    printf("\n enter radius and height of cone:");

    scanf("%f%f",&cor,&coh);

    cyv(cyr,cyh);

    cov(cor,coh);

}

void cyv(float cyr,float cyh)

{

    float v;

    v=3.14*cyr*cyr*cyh;

    printf("\n volume of cylinder:%f",v);

}

void cov(float cor,float coh)

{

    float v;

    v=3.14*cor*cor*coh/3;

    printf("\n volume of cone:%f",v);

}

Output:

enter radius and height of cylinder:4

4

 enter radius and height of cone:5

5

 volume of cylinder:200.960007

 volume of cone:130.833328
