Answer: [tex] (8)^2\pi\ feet^2[/tex]
or
[tex]64\pi \ feet ^2[/tex]
Step-by-step explanation:
We are given that the diameter of a circle = 16 feet
Then the radius of the circle = [tex]r=\dfrac{d}{2}=\dfrac{16}{2}=\ 8 feet[/tex]
Also, the area of a circle is given by :_
[tex]A=\pi r^2[/tex] , where r is radius of the circle .
For r = 8 feet
The area of the circle = [tex]\pi (8)^2=\pi (64)=64\pi \ feet ^2[/tex]
Hence, the expression that gives its area in square feet =
[tex] (8)^2\pi \ feet^2[/tex]
or
[tex]64\pi \ feet ^2[/tex]
