将度数转换为弧度的程序

鉴于度的角度，任务是将其转换成弧度。
例子：

Input: degree = 45 
Output: radian = 0.785398

Input: degree = 58
Output: radian = 1.01229

方法：
弧度：弧度是用于测量角度的SI单位，主要用于三角学中。弧度由圆弧定义。一个完整的圆刚好超过6个弧度(大约6.28)。一弧度略低于57.3度。
度：度，通常用°(度符号)表示，是平面角的量度，定义为完整旋转360度。因为完整旋转等于2 * pi弧度，所以一个度等于pi / 180弧度。
将弧度转换为度的公式是：

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

下面是上述方法的实现：

C++

// C++ program to convert degree to radian
 
#include 
#include 
using namespace std;
 
// Function for conversion
double Convert(double degree)
{
    double pi = 3.14159265359;
    return (degree * (pi / 180));
}
 
// Driver code
int main()
{
    double degree = 30;
    double radian = Convert(degree);
    cout << radian;
    return 0;
}

Java

// Java program to convert degree to radian
import java.io.*;
import java.util.*;
 
class GFG {
     
// Function for conversion
static double Convert(double degree)
{
    double pi = 3.14159265359;
     
    return (degree * (pi / 180));
}
 
// Driver code
public static void main(String[] args)
{
    double degree = 30;
    double radian = Convert(degree);
     
    System.out.printf("%.6f", radian);
}
}

Python3

# Python3 program to convert degree to radian
 
# Function for conversion
def Convert(degree):
 
    pi = 3.14159265359;
    return (degree * (pi / 180));
 
# Driver code
degree = 30;
radian = Convert(degree);
print(radian);

C#

// C# program to convert degree to radian
using System;
 
class GFG{
     
// Function for conversion
static double Convert(double degree)
{
    double pi = 3.14159265359;
     
    return (degree * (pi / 180));
}
 
// Driver code
public static void Main()
{
    double degree = 30;
    double radian = Convert(degree);
     
    Console.Write("{0:F6}", radian);
}
}

Javascript

 
// Javascript program to convert degree to radian
 
// Function for conversion
function Convert(degree)
{
    let pi = 3.14159265359;
    return (degree * (pi / 180));
}
 
// Driver code
 
    let degree = 30;
    let radian = Convert(degree);
    document.write(radian);
