<h3>Area of pen is 2462 square feet</h3>

<em><u>Solution:</u></em>

Given that,

Ellie needs new grass in the circular pen for her chickens

There is 175.84 feet of fencing around the circular pen

Therefore,

Circumference = 175.84 feet

<h3><u>The circumference of circle is given as:</u></h3>

$C = 2 \pi r$

Where, "r" is the radius of circle

$175.84 = 2 \times 3.14 \times r\\\\175.84 = 6.28 \times r\\\\r = \frac{175.84}{6.28}\\\\r = 28$

<h3><u>The area of circle is given as:</u></h3>

$Area = \pi r^2\\\\Area = 3.14 \times 28^2\\\\Area = 3.14 \times 784\\\\Area = 2461.76 \approx 2462$

Thus area of pen is 2462 square feet
