Answer:

A ≈ 201.06 ft.

Explanation:

To find the area, you use the formula A =
\pid².

In this case, it would be A =
(1)/(4) · 3.14 · 16² or A =
(1)/(4) · 3.14 · 256 = 201.06.

Hope this helps!! :)

Answer: 201.06 square feet

Explanation:

The radius of the circle is half of the diameter, so it is 8ft.

Then, we can use the area formula for a circle: 2πr

A = 64π square feet

A ≈ 201.06 square feet (rounded to the nearest hundredth)
