That is, a function that has a return statement and that returns the result of the calculation to the part of the program that called it. 1. Rewrite the function called circle area, it should take in the radius of a circle and return the area using the formula A=ar. Print the result of the returm. 2. Rewrite the function called rectangle_area, it should take in the length and width of a rectangle and return the area using the formula A = lw. Print the result of the return. 3. Rewrite the function called triangle_area, it should take in the base and height of a triangle and return the area using the formula A = Abh. Print the result of the return. 4.

Task #1 Application Download and Review This task will use the geometry.py source code file. It can be downloaded from Blackboard; it is incomplete. Since there is a large part of the program missing, the program will run but appear to do nothing except wait. In fact, it is waiting for end user input, but the end user does not have a menu to choose from. 1. Download the geometry.py file 2. Upload and then paste the source code into main.py of the online IDE. 3. Execute the source code. 4. Create a function called display menu that will simply print instructions for the user. a. The menu should appear to the user as follows: This is a geometry calculator Choose what you would like to calculate 1. Find the area of a circle 2. Find the area of a rectangle 3. Find the area of a triangle 4. Find the circumference of a circle 5. Find the perimeter of a rectangle 6. Find the perimeter of a triangle Enter the number of your choice: Task #5 Document and Submit Create a Word document. Create a table in the document and record the results of the manual calculations. Copy and paste the Python source code IDE Link for the void and value-returning functions. Input sample screenshots of the program's output. 5. Add code in the main function that calls the display_menu function, its location is indicated in the comments. 6. Debug, save, and run the program. a. Results should produce the menu, it should allow the user to choose any option, the result will always return zero. Submit the following via Blackboard: Python source code IDE Link for both solutions in the write submission tap. Word document with the following: Experiment results Python IDE links Screen output from at least one execution of the program Task #2 void functions For each of the following statements, write a function. 1. Write a function called circle_area that prompts the user for the radius of a circle and prints the area using the formula A =ar. 2. Write a function called rectangle_area that prompts the user for the length and width of a rectangle and prints the area using the formula A = lw. 3. Write a function called triangle_area that prompts the user for the base and height of a triangle and prints the area using the formula A = %bh.
