11111nata11111 [884]

Answer:

The answer is

<h2>660.5 square feet</h2>

Step-by-step explanation:

Area of a circle = πr²

where r is the radius

From the question

diameter = 29 feet

To find the radius given the diameter we use the formula

$radius = \frac{diameter}{2} \\ radius = \frac{29}{2} \\ = 14.5 \: \: feet$

So the area of the circle is

$A = {14.5}^{2} \pi \\ = 210.25\pi \\ = 660.519...$

We have the final answer as

<h3>660.5 square feet</h3>
