Answer:
[tex]9\pi ft^2[/tex]
Step-by-step explanation:
[tex]\text {Formula for the area of a circle:}\\ A=\pi r^2[/tex]
The diameter is given. The radius of a circle is half it's diameter.
[tex]6/2 = 3\\\text {Radius: } 3[/tex]
Apply the Formula (using 3.14 for pi):
[tex]A=\pi(3)^2\\A=\pi(9)\\A = 9\pi[/tex]
The answers are in exact form.
The circle's area should be [tex]9\pi ft^2[/tex].
I do not see C or D's options, but choose the answer that is the closest to [tex]9\pi[/tex].
