The formula for the area of a circle is $\pi$ $\times$ $r^{2}$ Substitute 14 for r and 3$\frac{1}{7}$ = $\frac{22}{7}$ for $\pi$ to obtain: A = $\frac{22}{7}$ $\times$ $14^{2}$ A = $\frac{22}{7}$ $\times$ 196 A = 22 $\times$ 28 A = 616 square meters. *Note, $\pi$ is about 3.1415, which we approximated as $\frac{22}{7}$.
