give me hint or guide me,please

### 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;

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 thatâ€™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;
}
