BEECROWD 1002 – Area of a Circle Question

Introduction

In this article, we will present a comprehensive solution for URI Online Judge problem 1002 in C, C++, Java, C#, and Python. This problem requires us to calculate the area of a circle given its radius. Our solution is optimized for efficiency and accuracy, and it can be easily adapted to different programming languages and platforms.

Solution Overview

Our solution consists of a single function that takes the radius as input and returns the area of the circle. The function uses the mathematical formula A = π . R² to calculate the area, where π is a constant value of 3.14159. The function is implemented in a way that maximizes performance and minimizes errors, making it suitable for large-scale calculations and real-time applications.

Solution Implementation

Here is the implementation of our solution in C, C++, Java, C#, and Python:

C

#include<stdio.h> 

int main() {

double R,A;

scanf("%lf",&R);
A=3.14159*R*R;
printf("A=%.4lf\n",A);

return 0;

}

C++

#include <iostream>
#include <iomanip>
#include <cmath>

using namespace std;

double calculate_area(double radius) {
    const double pi = 3.14159;
    return pi * pow(radius, 2);
}

int main() {
    double radius;
    cin >> radius;
    double area = calculate_area(radius);
    cout << fixed << setprecision(4) << "A=" << area << endl;
    return 0;
}

Java

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        double radius = input.nextDouble();
        double area = calculateArea(radius);
        System.out.printf("A=%.4f%n", area);
    }

    public static double calculateArea(double radius) {
        final double pi = 3.14159;
        return pi * Math.pow(radius, 2);
    }
}

Python

import math

def calculate_area(radius):
    pi = 3.14159
    return pi * radius ** 2

radius = float(input())
area = calculate_area(radius)
print(f"A={area:.4f}")
