write two functions that return the volume and weight of a disc. use the main function EXACTLY as below.

volume of a disc=((3.142*diameter*diameter)/4)*thickness.

weight of a disc=volume*density of the disc

#include

float disc_vol(float,float);

float dist_wt(float,float);

int main ()

{

float dia, thickness, density vol, wt;

printf("enter the diameter of the disc ");

scanf("%f",&dia);

printf("enter the thickness of the disc ");

scanf("%f", &thickness);

printf("enter the density of the disc ");

scanf("%f",&density);

vol = dis_vol(dia,thickness);

wt=disc_wt(vol,density);

printf("The volume of the disc is %f ", vol);

printf("the weight of the disc is %f ",wt);

printf("bye ");

}

sample output that you can check against

enter the diameter of the disc

5

enter the thickness of the disc

3

enter the density of the disc

3.8

the volume of the disc is 58.9124

the weight of the disc 223.867

bye

I need to write the functions below and make sure they're working ...what are the correct functions ?
