In this post, we will learn how to find the surface area of a sphere using C Programming language.
Surface area of a sphere is defined as the total area covered by its outer surface. A sphere has a surface area equal to 4πr2 square units.
- Surface area of sphere = 4πr2
We will be using the above formula in our program to find the surface area of a sphere.
So, without further ado, let’s begin this tutorial.
C Program to Find Surface Area of Sphere
// C Program to Find Surface Area of Sphere
#include <stdio.h>
int main(){
float radius, area;
float PI = 3.14;
// Asking for input
printf("Enter the radius of the sphere: ");
scanf("%f", &radius);
// Calculating Surface Area
area = 4 * PI * radius * radius;
// Display output
printf("Surface Area of Sphere: %.2f", area);
return 0;
}
Output
Enter the radius of the sphere: 3
Surface Area of Sphere: 113.04
How Does This Program Work ?
float radius, area;
float PI = 3.14;
In this program, we have declared three float data type variables named radius, area and PI.
// Asking for input
printf("Enter the radius of the sphere: ");
scanf("%f", &radius);
Then, the user is asked to enter the radius of the sphere.
// Calculating Surface Area
area = 4 * PI * radius * radius;
We calculate the surface area of the sphere by using the formula 4πr2.
// Display output
printf("Surface Area of Sphere: %.2f", area);
Finally, the surface area is displayed on the screen using printf() function.
Conclusion
I hope after going through this post, you understand how to find the surface area of a sphere using C Programming language.
