Answer:
28.26 ft²
Explanation:
The equation for the area of a circle is:
A = πr²
Plug in 3 for r:
A = π(3²) = 9π ≈ 28.27
The answer says 28.26, but it should be rounded to 28.27. I recommend pointing this out to your teacher!
28.26
The area of a circle is πr^2. So all you would do you be π times 3 to the power of 2 to get abour 28.26.
