Per NCERT's discussion of why π is BIGGER than 3 (Mesopotamian observation, c. 1900 BCE), what shape did they compare with a circle to reach this conclusion?
AA square
BA pentagon
CAn octagon
DA hexagon inscribed in the circle (which has perimeter 6r and is shorter than the circle's perimeter 2πr — proving πr > 3r so π > 3)
Answer & Solution
Correct answer: D. A hexagon inscribed in the circle (which has perimeter 6r and is shorter than the circle's perimeter 2πr — proving πr > 3r so π > 3)
Per NCERT, the inscribed hexagon (perimeter 6r < 2πr) showed π > 3. The other polygons are not the Mesopotamian comparison used in the chapter.
