A≈201.06m²

Using the formulas

A=πr2

d=2r

Solving forA

A=1

4πd2=1

4·π·162≈201.06193m²

Answer:


C)~ 64 \pi~\text{m}^2

Explanation:


\text{Area of circle}= \pi * \text{Radius}^2\\\\\\~~~~~~~~~~~~~~~~~~= \pi \left( \frac{\text{Diameter} }{2} \right)^2\\\\\\~~~~~~~~~~~~~~~~~~=\pi \left( (16)/(2)\right)^2\\\\\\~~~~~~~~~~~~~~~~~~=\pi \cdot8^2\\\\\\~~~~~~~~~~~~~~~~~~=64 \pi~\text{m}^2
