How can you estimate the area of a circle? - Answers

Remember the circle eq'n A = pi r^2 pi ~ 3.14 pi ~ 3/1412592 Are values of 'pi' you may be given in school/college. However , since 'pi' is an irrational number, the values given are approximations. So it follows any area calculated in an approximation. So if the radius is say 5 units. Then A = 3.14 X 5^2 = 78.5 units^2 This is an approximation. !!!! As mentioned above 'pi' is an irrational number, which means the decimals go on to inifinty and there is no regular order in the decimalk digits. 'pi' has been calculated to 50 billion places and still going. A pocket calculator will gice pi ~ 3.1415926545.... So any calculation using 'pi' results in an approximation.
