#include <math.h>  //header file for math functions

#define pi 3.1415     //using macro

#include <stdio.h>  //header file for printf() or scanf()

int main()   //main function

{  

   double radius;  //radius is a double type variable

   float surface_area, vol;    //surface_area andvolume is a float type variable

   printf("Enter the radius of the sphere : \n");     //printf() is use to print an output

   scanf("%lf", &radius);   //scanf() is use to take input from the user

   surface_area =  4 * pi * pow(radius,2);

   vol = (4.0/3) * pi * pow(radius,3);

   printf("The Surface area of the sphere is: %.3f", surface_area); // display surface area

   printf("\n Volume of the sphere is : %.3f", vol); // display volume

   return 0;  

}

Output:

Enter radius of the sphere : 4.4

Surface area of sphere is: 243.278
