Scope

Do one of the following programming problems:

Population

Write a function called estimate_population(starting_population, years_later) which will estimate how large a population will be after years_later, if it has the specified starting population. Assume there is 1 birth every 7 seconds, and a death every 12 seconds. 







  
Ring Area



  Write two functions:



    
  
  1. circle_area(radius) that returns the area of a
    circle with the specified radius.
    2. 
  
  2. ring_area(inner_radius, width) that returns the area
    of the ring with the specified radius and width.  This function
    should call the circle_area function.  The following
    image illustrates the inner radius and width of a ring.
