Answer
$\color{blue}{A\approx 365.3 \space m^2}$
Work Step by Step
RECALL:
The area of a sector $(A)$ intercepted by a central angle $\theta$ on a circle whose radius is $r$ is given by the formula:
$A = \frac{1}{2}r^2\theta$, where $\theta$ is in radian measure.
Convert the angle to radians to obtain:
$125^o
\\=125^o\cdot \dfrac{\pi}{180^o}
\\=\dfrac{25\pi}{36}$
Substitute the given values of the radius and $\theta$ to obtain:
$A=\frac{1}{2}r^2\theta
\\A=\frac{1}{2}(18.3^2)(\frac{25\pi}{36})
\\A=365.3083208
\\\color{blue}{A\approx 365.3 \space m^2}$
