[tex]C)~ 64 \pi~\text{m}^2[/tex]

Step-by-step explanation:

[tex]\text{Area of circle}= \pi \times \text{Radius}^2\\\\\\~~~~~~~~~~~~~~~~~~= \pi \left( \dfrac{\text{Diameter} }{2} \right)^2\\\\\\~~~~~~~~~~~~~~~~~~=\pi \left( \dfrac{16}{2}\right)^2\\\\\\~~~~~~~~~~~~~~~~~~=\pi \cdot8^2\\\\\\~~~~~~~~~~~~~~~~~~=64 \pi~\text{m}^2[/tex]

A≈201.06m²

Using the formulas

A=πr2

d=2r

Solving forA

A=1

4πd2=1

4·π·162≈201.06193m²
