Correct. The diameter of the circle is 14 meters. The radius is half of this. Therefore, substitute $\displaystyle{r}={7}\usepackage{cmbright}\Huge\$ into the formula $\displaystyle{A}=\pi{{r}}^{{2}}\usepackage{cmbright}\Huge\$ to find the area of the circle.

$\displaystyle{A}=\pi{{\left({7}\right)}}^{{2}}\usepackage{cmbright}\Huge\$

$\displaystyle{A}=\pi\cdot{49}\usepackage{cmbright}\Huge\$

$\displaystyle{A}\approx\frac{{22}}{{7}}\cdot{49}={154}\usepackage{cmbright}\Huge\$

The area of the circle is approximately 154 square meters.
