In this post, we will learn how to find the area of an ellipse using C Programming language.
The area of an ellipse is defined as the amount of region present inside it.
- Area of Ellipse = π a b,
where,
a = length of semi-major axis
b = length of semi-minor axis
So, without further ado, let’s begin this tutorial.
C Program to Find Area of Ellipse
// C Program to Find Area of Ellipse
#include <stdio.h>
#define PI 3.14
int main(){
float major, minor, area;
// Asking for input
printf("Enter the minor axis: ");
scanf("%f", &minor);
printf("Enter the major axis: ");
scanf("%f", &major);
// Calculating area of ellipse
area = PI * minor * major;
// Displaying output
printf("Area of Ellipse: %.2f", area);
return 0;
}
Output
Enter the minor axis: 7
Enter the major axis: 15
Area of Ellipse: 329.70
How Does This Program Work ?
float major, minor, area;
In this program, we have declared three float data type variables named major, minor and area.
// Asking for input
printf("Enter the minor axis: ");
scanf("%f", &minor);
printf("Enter the major axis: ");
scanf("%f", &major);
Then, the user is asked to enter the value of the major axis and minor axis.
// Calculating area of ellipse
area = PI * minor * major;
We calculate the area using the formula π a b, where,
a = length of semi-major axis
b = length of semi-minor axis
Π – 3.14
// Displaying output
printf("Area of Ellipse: %.2f", area);
Finally, the area is printed using the printf() function. Here, we have used %.2f format specifier because we want to display the output only till 2 decimal places.
Conclusion
I hope after going through this post, you understand how to find the area of an ellipse using C Programming language.
