Question

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<stdio.h>
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 ? 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<stdio.h>
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 ");
}

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

Explanation / Answer

Answer:

functions can be written as below:

float dis_vol(float dia,float thickness) // takes diameter and thickness as parameter
{
return ((3.142*dia*dia)/4)*thickness; // returns the disc volume to the function
}

float disc_wt(float vol,float density) //takes the volume and density as the parameter
{
return vol*density; //returns the disc weight to the function
}

THUS THE WHOLE PROGRAM CAN BE WRITTEN AS:

#include<stdio.h>

float dis_vol(float dia,float thickness)
{
return ((3.142*dia*dia)/4)*thickness;
}

float disc_wt(float vol,float density)
{
return vol*density;
}

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); //function dis_vol is called here and assigned to variable vol

wt=disc_wt(vol,density);   // function disc_wt is called here and assigned to variable wt

printf("The volume of the disc is %f ", vol); //prints the volume calculated by the function

printf("the weight of the disc is %f ",wt); //prints the weight calculated by the function

printf("bye ");

}

output:

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
