In your journal, you identified careers that involve irrational numbers. You brainstormed or researched jobs that use pi or Euler’s number to do their work.

Question

Imagine that your friend loves to plan parties, and he wants to be an event planner someday. He does not think he needs to know how to find a number between two rational numbers. He also says he will never use pi again in his life after math class. You think of some of the tasks he might need to do as an event planner:

Decide how many cakes to order

Answer 1

Determining how many cakes to order for an event might seem like a straightforward task, but it actually involves some understanding of numbers and calculations. An event planner needs to consider the number of guests attending the event and estimate the quantity of cake slices each guest will have.

However, if your friend claims not to need to know how to find a number between two rational numbers, it might be challenging for him to make accurate estimates. Understanding irrational numbers, such as pi, can help in determining the number of cake slices from a given cake size, ensuring that there is enough for all guests. Pi is commonly used to calculate the circumference and area of round cakes, allowing the event planner to accurately assess the number of portions each cake can yield.

Additionally, knowledge of pi and other irrational numbers can help an event planner come up with creative cake designs involving geometric shapes. These designs can be eye-catching and add an element of uniqueness to the event.

While it may be possible for someone to become an event planner without explicitly using irrational numbers, having a solid mathematical foundation, including knowledge of pi, can greatly assist in performing various tasks efficiently and accurately.
