There's missing information. What does f(x) approach as x approaches negative infinity and infinity?
B is the only answer that would make sense.
Since it's a wall, I'm guessing it will only have access to half the circle? Therefore:
<em>Circle area formula: </em>πr²
<em>Radius:</em> 12/2 = 6ft
<em>Our case:</em>
(π * 6²)/2 =
36π/2 =
18π = 56.55ft²
A and B are the answers.
If you need proof, just ask in the comments, and I’ll get back to you.
I hope this helps!
