URI 1002 solution video:

See a video to solve URI 1002 problem solution in C language if you want:

### URI Solution 1002 Code in C:

`#include<stdio.h>int main(){    double R,A;    scanf("%lf", &R);    A = 3.14159 * R * R;    printf("A=%.4lfn", A);    return 0;}`

### URI Solution 1002 Code / URI 1002 solution in CPP:

`#include <iostream>#include <iomanip>using namespace std;int main(){    double R,A;    cin >> R;    A = 3.14159 * R * R;    cout << "A=" << fixed << setprecision(4) << A << endl;    return 0;}`

### URI Solution 1002 Code / URI 1002 solution in Java:

`import java.util.Scanner;public class Main {    public static void main(String[] args){        double R,A;        Scanner sc = new Scanner(System.in);        R = sc.nextDouble();        A = 3.14159 * R * R;        System.out.printf("A=%.4fn",  A);`
`   }}`

### URI Solution 1002 Code / URI 1002 solution in  Python:

`raio = float(input())area = (raio * raio) * 3.14159 print("A=%0.4f" %area)`

### URI Solution 1002 Code / URI 1002 solution in  C# (C Sharp):

`using System;class URI {    static void Main(string[] args) {        double radio, area;        radio = Convert.ToDouble(Console.ReadLine());        area = 3.14159 * (radio * radio);        Console.WriteLine("A="+area.ToString("0.0000"));        Console.ReadKey();    }}`

Or In Another in C#

using System;
class URI {
static void Main(string[] args) {
double A = 3.14159 * R * R;
Console.WriteLine(“A={0:0.0000}”, A);
}
}

Demonstration:

We’ve just implemented the logic of are calculating in this line in C and most provably same line in other languages,

`A = 3.14159 * R * R;`

Area of a circle we know that = (π * r2)
That means = pi * radius2
Just implement this in coding. Since having any problem just put a comment below. Thanks
