Answer:
113.04
Step-by-step explanation:
Since the diameter of a circle is twice the radius, the radius of this circle must be 12/2=6ft. Using the area formula:
[tex]A=\pi r^2 =3.14 \cdot 6^2=113.04 \text{ ft}^2[/tex]
Hope this helps!
area = (pi)r^2
r = radius = diameter/2
r = 12 ft/2 = 6 ft
area = 3.14 * (6 ft)^2
area = 3.14 * 36 ft^2
area = 113.04 ft^2
