  • Exercise \(\PageIndex{1}\)

    Write a definition for a class named Circle with attributes center and radius, where center is a Point object and radius is a number.

    Instantiate a Circle object that represents a circle with its center at \( (150,100) \) and radius \(75\).

    Write a function named point_in_circle that takes a Circle and a Point and returns True if the Point lies in or on the boundary of the circle.

    Write a function named rect_in_circle that takes a Circle and a Rectangle and returns True if the Rectangle lies entirely in or on the boundary of the circle.

    Write a function named rect_circle_overlap that takes a Circle and a Rectangle and returns True if any of the corners of the Rectangle fall inside the circle. Or as a more challenging version, return True if any part of the Rectangle falls inside the circle.
