Per NCERT, ARCHIMEDES of Syracuse (250 BCE) 'trapped' π between two values — using what method?
AComputing the perimeters of polygons INSCRIBED in and CIRCUMSCRIBED about a circle (he used up to 96-sided polygons)
BCalling it √10
CUsing an infinite series
DMeasuring real circles with a string
Answer & Solution
Correct answer: A. Computing the perimeters of polygons INSCRIBED in and CIRCUMSCRIBED about a circle (he used up to 96-sided polygons)
Archimedes used inscribed + circumscribed polygons (per NCERT). The other options misstate his method.
