This requires using the cylindrical shells method, and the cross section method to prove that the volume of any two “napkin rings” is the same. Extremely thorough reasoning, must pay attention to everything mentioned in the assignment, and be able to translate it into simpler terms. Must properly format and show mathematical work as well. Able to use the video mentioned in first file for background, I will attach my first paper as well for reference to proper mathematical format. If the pdfs are opened in word, there will be format issues.
