Write a program that accepts a circle's radius request as input and calculates the following:
The radius (r)
The diameter (2r)
The circumference (2Tr)
The area (TTr2)
Python code:
print("\nAssignment 2\n")
radius = 0.0
diameter = 0.0
circumference = 0.0
area = 0.0
radius = float(input("What is the radius of the circle?: "))
diameter = radius * 2
circumference = round(2 * pi * radius, 2)
area = round(pi * radius ** 2, 2)
print("\nThe radius of the circle is: ", radius)
print("\nThe diameter of the circle is: ", diameter)
print("\nThe circumference of the circle is: ", circumference)
print("\nThe area of the circle is: ", area)
Write the C++ version of the given Python program
Output if the input value is 4

Assignment 2
Enter the radius of a circle: 4
The radius of the circle is: 4
The diameter of the circle is: 8
The circumference of the circle is: 25.176
The area of the circle is: 50.352
Notes:
Include the following header file:
#include <cmath>
// to import mathematical functions
Declare Pl as follows in the main function:
const double PI = 3.147;
How to call the pow function in C++:
area = PI * pow(radius,2);
Test data:
Use the value of 2.5 as radius.

The credit plan at TidBit Computer Store specifies a 10% down payment and an annual interest rate of 12%. Monthly payments are 5% of the listed purchase price, minus the down payment. Write a program that takes the purchase price as input. The program should display a table, with appropriate headers, of a payment schedule for the lifetime of the loan. Each row of the table should contain the following items: The month number (beginning with 1) The current total balance owed The interest owed for that month The amount of principal owed for that month The payment for that month The balance remaining after payment The amount of interest for a month is equal to balance × rate / 12. The amount of principal for a month is equal to the monthly payment minus the interest owed.

For example, 145 is a Special Number because 145 = 1! + 4! + 5!.Your task is to write a Python code that takes some numbers as user input (separated by a comma) in a single line and groups the Special & Non-Special numbers in a dictionary. Note that the values corresponding to the keys in that dictionary must be in tuple format.Sample Input 1:145, 346, 2, 83221, 7999888Sample Output 1:{'Special': (145, 2), 'Non-Special': (346, 83221, 7999888 )}-----------------------------------------------------------------Sample Input 2:1431, 69716, 353, 7969828Sample Output 2:{'Special': (), 'Non-Special': (1431, 69716, 353, 7969828)}arrow_forwardPython programming This example misses indentations, rewrite the code.
