Who is given credit for discovering pi?

Answer 1

The concept of pi (π) has been known since ancient times, with various civilizations approximating its value. The earliest recorded approximation comes from the ancient Egyptians and Babylonians around 2000 BCE. However, the Greek mathematician Archimedes is often credited with providing one of the first rigorous calculations of pi around 250 BCE, using inscribed and circumscribed polygons to estimate its value. Thus, while no single person "discovered" pi, Archimedes' contributions significantly advanced its understanding.
