Answer:


\begin{gathered} A\approx201.06m^2 \\ C\approx50.27\text{ m} \\ \text{Answer is C} \end{gathered}

Explanation:

The area of a circle is represented by the following equation:


\begin{gathered} A=\pi\cdot r^2 \\ \text{where,} \\ r=\text{ radius} \end{gathered}

Hence, if the radius is 8 meters.


\begin{gathered} A=\pi\cdot(8)^2 \\ A=64\pi \\ A\approx201.06m^2 \end{gathered}

Now, the circumference is given as:


\begin{gathered} C=2\pi\cdot r \\ C=2\pi(8) \\ C\approx50.27\text{ m} \end{gathered}
