Write a Python program to create a class Circle with an attribute for radius. Write methods calculate_area and calculate_circumference to calculate the area and circumference of the circle, respectively.
Example 1:
Input: circle = Circle(3) Output: Area: 28.27, Circumference: 18.85
Example 2:
Input: circle = Circle(5) Output: Area: 78.54, Circumference: 31.42
Define the class Circle and initialize radius in the __init__ function. Then, create the methods calculate_area and calculate_circumference and use the mathematical formulae for the area and circumference of a circle.
import math
class Circle:
def __init__(self, radius):
self.radius = radius
def calculate_area(self):
return round(math.pi * (self.radius ** 2), 2)
def calculate_circumference(self):
return round(2 * math.pi * self.radius, 2)
circle = Circle(3)
print('Area:', circle.calculate_area()) # Output: Area: 28.27
print('Circumference:', circle.calculate_circumference()) # Output: Circumference: 18.85
circle = Circle(5)
print('Area:', circle.calculate_area()) # Output: Area: 78.54
print('Circumference:', circle.calculate_circumference()) # Output: Circumference: 31.42
