My code

#include <bits/stdc++.h>
using namespace std;

int main() {

  double pi = 3.14;
  double radius = 8.9;      //radius has to be declared as a 'double'
  double area = pi * radius * 2;
  cout << "The Area of the given Circle is ";
  cout << area;
  
  return 0;
}

The formula for finding area of a circle is not correct in your code.

The formula is; [ area = (pi * r * r) or, (pi * r-squared) ].

In your code, you are using formula for finding the circumference of a circle that’s why code is not being correct.

Here is my code for reference.

#include <bits/stdc++.h>
using namespace std;

int main() {

  double pi = 3.14;
  double radius = 8.9;      //radius has to be declared as a 'double'
  double area = pi * radius * radius;
  cout << "The Area of the given Circle is ";
  cout << area;
  
  return 0;
}
