What is a model?

  • A mathematical model is a system description that employs math ideas and language.
  • Mathematical modeling is the process of creating a mathematical model.
  • Mathematical models are used in the natural sciences (physics, biology, earth science, chemistry), engineering disciplines (computer science, electrical engineering), and non-physical structures such as the social sciences (such as economics, psychology, sociology, political science).
  • A large part of the field of operations research is the use of statistical equations to solve problems in business or military operations.
  • Music, linguistics, and philosophy all use mathematical models (for example, intensively in analytic philosophy).
  • A model is, for example, the method for the area of a circle, πr2.

Therefore, πr2 is an example of (D) a model.
