Title: 
How area changes with diameter

Description: 
  • Ensino Médio::Matemática
  • It is easy to believe that when you change one dimension of a figure, its area changes by the same percentage. However, this is incorrect. The area of a circle changes with the square of its diameter. For example, doubling the diameter quadruples the area. Another example: tripling the diameter makes the area go up by a factor of nine
