SUPyF2 Objects/Classes-Lab - 05. Circle

Problem:
Create a class Circle. In the __init__ method the circle should only receive one parameter (its diameter).
Create a class attribute called __pi that is equal to 3.14. The class should also have the following methods:
• calculate_circumference() - returns the circumference of the circle
• calculate_area() - returns the area of the circle
• calculate_area_of_sector(angle) - given the central angle in degrees, returns the area that fills the sector
Notes: Search the formulas in the internet. Name your methods and variables exactly as in the description!
Submit only the class. Test your class before submitting!

Example:
Test Code:

circle = Circle(10)
angle = 5

print(f"{circle.calculate_circumference():.2f}")
print(f"{circle.calculate_area():.2f}")
print(f"{circle.calculate_area_of_sector(angle):.2f}")

Output:
15.70
78.50
1.09
