He discovered the formula for the area of a circle, which led to the development of the formula for circumference.• Ancient Rome: The Roman astronomer Hipparchus (c.

190 BC – c. 120 BC) is believed to have calculated the circumference of the Earth, using the method of circumscribing circles around an inscribed polygon. His estimate was remarkably close to the actual value.• Medieval Period: During the Middle Ages, mathematicians such as Fibonacci (1170-1250) and Gerard of Cremona (1114-1187) made significant contributions to the field of geometry, including the calculation of circumference.• Renaissance: The Italian mathematician Luca Pacioli (1445-1517) wrote extensively on the subject of geometry, including the calculation of circumference.

His work built upon the discoveries of earlier mathematicians.• Modern Era: The development of calculus in the 17th century by mathematicians such as Sir Isaac Newton (1643-1727) and German mathematician Gottfried Wilhelm Leibniz (1646-1716) led to the discovery of the formula for the circumference of a circle in terms of its derivative.• 19th Century: The German mathematician Carl Friedrich Gauss (1777-1855) made significant contributions to the field of geometry, including the development of the Gaussian curvature, which is related to the calculation of circumference.• 20th Century: The development of computer algorithms and numerical methods in the 20th century enabled the efficient calculation of circumference for complex shapes, revolutionizing fields such as computer-aided design (CAD) and computational geometry.
