Answer 2

• Pi, denoted by the symbol π, is a mathematical constant that represents the ratio of the circumference of a circle to its diameter.
• It is an irrational number, which means that it cannot be expressed as a finite or repeating decimal. Its decimal representation goes on infinitely without any pattern.
• Pi is a fundamental constant in mathematics and appears in many areas of science and engineering, including geometry, trigonometry, calculus, and physics.
• It is also used in many practical applications, such as in calculating the area and volume of circular shapes, designing and building structures, and encoding and transmitting data.
• Pi is sometimes also referred to as Archimedes' constant or Ludolph's number, after the ancient Greek mathematician Archimedes and the German mathematician Ludolph van Ceulen, who both made significant contributions to its calculation and approximation.
