Question

What is the best approximation for the area of a circle with a diameter of 19 meters?

Answer 1

$A = \pi r^{2}$ 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 $283.4 m^{2}$
