Answer:
28.26 ft.²
Step-by-step explanation:
Mathematics: <u>Explain/formula.</u>
To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.
Mathematics: <u>Solve.</u>
Here, the diameter is 6 ft.
To find the radius, divide the diameter by 2.
Now, we can plug the numbers into the formula.
Mathematics: <u>Conclude.</u>
Therefore, the area of this circle is 28.26 ft.²
