Define a macro with one parameter to compute the volume of a sphere.

Define a macro with one parameter to compute the volume of a sphere. Write a C program using this macro to compute the volume for spheres of radius 5, 10 and 15 meters.

Program Code:

#include<stdio.h>

#include<math.h>

#define PI 3.142

#define volume(r) ((4/3.0)*PI*pow(r,3))

void main()

{

int r;

float v;

scanf("%d",&r);

v=volume(r);

printf("\n volume of the sphere v=%.3f",v);

}
