If the area of a circle is 16 meters what is the radius in meters

Answer 1

If the area of a circle is 16 meters what is the radius in meters

From the formula $S = \pi r^2$ (where $r$ is radius, $S$ is area), we can find radius $r$ :

$$r ^ {2} = \frac {S}{\pi}, r = \sqrt {\frac {S}{\pi}} = \sqrt {\frac {1 6}{3 . 1 4}} = 2. 2 6 m$$
