Answer:

200.96 ft²

Explanation:

Step 1: Define/formula

To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.


a=\pi r^2(3.14*radius*radius)

Step 2: Solve

According to the word problem, the radius is 8.

From here, we plug the numbers into the formula.


\pi 8^2(3.14*8*8)=200.96ft^2.

Step 3: Conclude

Therefore, the area of this circle is 200.96 ft.²
