C program for area of a sphere

Write a c program to find the volume and surface area of sphere

C program for area of a sphere

C code:

#include<stdio.h>

#include<math.h>

int main(){

    float r;

    float surface_area,volume;

    printf("Enter radius of the sphere : ");

    scanf("%f",&r);

    surface_area =  4* M_PI * r * r;

    volume = (4.0/3) * M_PI * r * r * r;

    printf("Surface area of sphere is: %.3f",surface_area);

    printf("\nVolume of sphere is : %.3f",volume);

    return 0;

}

Sample output:

Enter radius of the sphere: 5

Surface area of sphere is: 314.159

Volume of sphere is: 523.599

 

Formula of surface area of sphere:

Surface_area = 4 * Pie * r²

Formula of volume of sphere:

Volume = 4/3 * Pie * r³

Pie = 22/7 or 3.1415926535...
