Find Area of an Ellipse Using C++

An ellipse is the locus on all those points in a plane such that the sum of their distance from two fixed points in the plane is constant.

Where the fixed point is known as foci, which are sounded by the curve, the fixed line is a directrix, and the constant ratio is the eccentricity of the ellipse.

Area of an Ellipse

The area of an ellipse is the region enclosed by the ellipse. Which is computed by the following formula:

Area = ??a?b

Let's discuss the following key points of an ellipse:

C++ Program to Find Area of an Ellipse

In this example, we write a program to find the area of an ellipse using the following formula (??a?b) in C++:

#include <iostream>
#include <cmath>
using namespace std;

float get_area(float a, float b) {
   return M_PI * a * b;
}
int main() {
   float a = 5.0, b = 4.0;
   cout << "Area of ellipse: " << get_area(a, b) << endl;
   return 0;
}

Output

The above code generates the area of an ellipse ?
