The formula to find area of a circle is [tex]a = \pi r^2[/tex]
As you can see, the diameter of your circle is 24 ft. The radius of a circle is half the diameter, so [tex]r=12[/tex] ft.
Assuming that [tex]\pi =3.14[/tex],
We can plug in the values.
[tex]a=\pi r^2 = \pi *(12)^2[/tex]
[tex]a= 452.2 ft^2[/tex]
The answer is D. 452.2 ft^2.
