Answer:

Step-by-step explanation:

The area of a circle is

[tex]A=\pi r^2[/tex]

We are given the diameter, but need the radius.  The radius is half the diameter, so the radius is 8 feet.  Plugging into the formula and using 3.14 for π:

A = (3.14)(64) so

A = 200.96 sq feet which rounds to 201.  I guess that's the first choice there, but not quite exact...
