# Write a function that gets the radius of a circle, # and displays and returns # the approximation of the circle's area. # Use 3.14 as the value for pi. # Write a function that gets a number and # determines if the number is even or odd. # The program should return "odd" if the number is odd, # and "even" if the number is even. Hint: use modulus! # Write a function that gets a number and # determines if the number is even or odd. # The program should return 2 things: # 1. return the given number # 2. return "odd" if the number is odd, # and "even" if the number is even # Write a function that gets 5 numbers, # computes and returns the following: # 1. sum of the numbers # 2. average of the numbers # Rewrite the previous function into 3 small functions # The first function (called compute_sum) # computes and return a sum of the numbers. # The second function (called compute_average) # computes and return an average of the numbers. # The third function gets 5 numbers, # calls compute_sum and compute_average functions, # and returns the following: # 1. sum of the numbers # 2. average of the numbers # consider # 1. where the functions are defined # 2. where the functions are called # 3. flow of the function calls
