What is the best approximation for the area of a circle with a diameter of 19 meters?
FromTheMoon [43]
A = \pi r^{2} is the equation used for determining area from radius.  We're given diameter, so to get the radius simply divide by 2. 19/2 = 9.5.

A = (3.14)(9.5)^{2}, when solved, equals 283.385 m^(2).  After rounding to the nearest tenth, we get 283.4 m^{2}
