Answer:
A = π × 4 or if you want to substitute pi for 3.14, A = 12.56
Explanation:
The area of a circle is A = π × r²
We substitute the of r with 2 (because the radius, r, is half of the circumference)
Next, we square 2, which is equal to 4.
Now, we can substitute π with 3.14 (if that's what the question is asking you to do).
We multiply 4 by 3.14 and get 12.56.
The area, A, is equal to 12.56 in².
Hope this helps!
