Value of Irrational Number π (Part 1)

Click For Summary

Discussion Overview

The discussion centers around the value of the irrational number π and its comparison to the quantity \((4/3)^4\). Participants explore whether this comparison can be made without the use of a calculator, specifically in terms of decimal place agreement.

Discussion Character

  • Exploratory, Homework-related, Mathematical reasoning

Main Points Raised

  • One participant states that the value of π, correct to ten decimal places, is 3.1415926535 and questions how \((4/3)^4\) compares to this value.
  • Another participant suggests that the question can be answered without a calculator and proposes using long division to compute \((4/3)^4\) as \(\frac{256}{81}\) to a few decimal places.
  • Some participants express confusion about the original question's clarity regarding the use of a calculator.
  • There is a mention of the historical value of π used in the Rhind papyrus, linking it to the calculation of \((4/3)^4\).

Areas of Agreement / Disagreement

Participants generally agree on the need to clarify the question regarding the use of a calculator, but there is no consensus on the method of comparison or the necessity of using a calculator for the task.

Contextual Notes

Some participants note that the original question was edited, indicating potential changes in the scope or clarity of the inquiry.

The value of irrational number π, correct to ten decimal places (without rounding), is 3.1415926535. By using your calculator, determine to how many decimal places the following quantity [(4/3)^4] agrees with π.

The value used for π in the Rhind papyrus, an ancient Babylonian text written about 1650 B.C. is (4/3)^4.

I was wondering if this question can be answered without a calculator. Can we show that (4/3)^4 in terms of decimal places agrees with pi?

Then this should be said in the original question to not make people guess.

You can use long division to compute $$\left(\frac43\right)^4=\frac{256}{81}$$ to a few decimal places.
