Your friend might actually need to use irrational numbers, such as pi, when choosing a round table for events. The reason is that the size of a round table is often determined by its diameter. To ensure that six people can comfortably fit around the table, your friend will need to calculate the appropriate diameter.
The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius. Since your friend wants to find the diameter, which is twice the length of the radius, he can rearrange the formula to solve for the diameter:
D = 2r
D = 2(C/2π)
D = C/π
By knowing the circumference needed to accommodate six people, your friend can divide it by pi to find the appropriate diameter of the round table.
So even as an event planner, a basic understanding of pi and how to use it will be beneficial for your friend when it comes to choosing round tables for parties.
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.
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:
Choose a round table that is the correct size to fit six people
