Finger Exercise Lecture 17

Write the class according to the specifications below:

class Circle():
    def __init__(self, radius):
        """ Initializes self with radius """
        # your code here

    def get_radius(self):
        """ Returns the radius of self """
        # your code here

    def set_radius(self, radius):
        """ radius is a number
        Changes the radius of self to radius """
        # your code here

    def get_area(self):
        """ Returns the area of self using pi = 3.14 """
        # your code here

    def equal(self, c):
        """ c is a Circle object
        Returns True if self and c have the same radius value """
        # your code here

    def bigger(self, c):
        """ c is a Circle object
        Returns self or c, the Circle object with the bigger radius """
        # your code here
