how would a party planner use pi to choose a round table that is correct to fit a size of 6 people

1 answer

To choose a round table that can comfortably accommodate a size of 6 people, a party planner can use the mathematical constant π (pi) to determine the appropriate diameter of the table. Here’s how to go about it:

  1. Determine Space Per Person: Generally, a comfortable amount of space per person at a round table is about 24 inches (2 feet) in diameter. This allows for enough room for seating and movement.

  2. Calculate the Table's Circumference:

    • Since the table is round, we'll be using the circumference formula: \[ C = n \times d \] where \( n \) is the number of people and \( d \) is the space required per person.
    • For 6 people, if we allocate 2 feet (24 inches) per person, we calculate the total circumference needed: \[ C = 6 \times 24, \text{inches} = 144, \text{inches} \]
  3. Find the Diameter Using the Circumference:

    • We know the relationship between the circumference \( C \) and the diameter \( d \) is given by the formula: \[ C = \pi \times d \]
    • Rearranging this, we can solve for \( d \): \[ d = \frac{C}{\pi} \]
    • Plugging in our calculated circumference: \[ d = \frac{144, \text{inches}}{\pi} \approx \frac{144}{3.14} \approx 45.8, \text{inches} \]
  4. Select the Table Size:

    • The diameter of the round table should be approximately 46 inches to comfortably seat 6 people. Depending on available tables, the planner could round up to the nearest standard table size, such as 48 inches.
  5. Consider Additional Space: It's also good to factor in a little extra space for comfort, so opting for a table slightly larger than calculated can be beneficial.

By using π in the above calculations, the party planner ensures they choose a round table that is not only mathematically suitable but also practically comfortable for the guests.
