The Babylonian approximation of pi as 25/8, dated to around 1900 BCE, deviated from the true value of pi by roughly what margin?
Answer
Less than 0.5%
The fraction 25/8 equals 3.125, which is less than half a percent away from pi's actual value of approximately 3.14159, an impressively accurate estimate for its era.
💡 Did you know?
Ancient Babylonians approximated π as 25/8 around 1900 BCE, missing the true value by less than 0.5%—without algebra or modern notation.
