将弧度转换为度的程序

在转向实际解决方案之前，让我们尝试找出什么是度数，弧度及其关系。
弧度：弧度是角度量度的标准单位，在许多数学领域中都使用。单位圆弧的弧长在数值上等于其对角的弧度测量值。一弧度略低于57.3度。
度数：度数(以度为单位，以弧度，弧度或弧度表示)，通常用°(度数符号)表示，是平面角的量度，定义为使整个旋转为360度。
关系2pi * rad = 360°可以使用弧长公式得出。
与该圆的半径相同长度的圆弧的对角为1弧度。圆周对角为2pi弧度。
因此，公式为：

degree = radian * (180/pi)
where, pi = 22/7

例子：

Input : radian = 20
Output : degree = 1145.4545454545455
Explanation: degree = 20 * (180/pi)

Input : radian = 5
Output : degree = 286.3636363636364
Explanation : degree = 20 * (180/pi)

注意：在此程序中，我们将pi的值设为3.14159，以获取所有三种语言的标准结果。

C

// C code to convert radian to degree
 
#include 
 
// Function for convertion
double Convert(double radian){
    double pi = 3.14159;
    return(radian * (180/pi));
}
 
// Driver Code
int main(){
    double radian = 5.0;
    double degree = Convert(radian);
    printf("%.5lf", degree);
    return 0;
}

Java

// Java code to convert radian to degree
 
import java.io.*;
class GFG {
    // Function for convertion
    static double Convert(double radian){
        double pi = 3.14159;
        return(radian * (180/pi));
    }
    // Driver Code
    public static void main (String[] args) {
        double radian = 5.0;
        double degree = Convert(radian);
        System.out.println("degree = "+ degree);
    }
}

Python3

# Python code to convert radian to degree
 
# Function for convertion
def Convert(radian):
    pi = 3.14159
    # Simply used the formula
    degree = radian * (180/pi)
    return degree
 
# Driver Code
radian = 5
print("degree =",(Convert(radian)))

C#

// C# code to convert radian to degree.
using System;
 
class GFG {
 
    // Function for convertion
    static double Convert(double radian){
        double pi = 3.14159;
        return(radian * (180 / pi));
    }
 
    // Driver Code
    public static void Main () {
        double radian = 5.0;
        double degree = Convert(radian);
        Console.Write("degree = " + degree);
    }
}
