ANSWER:

The area of the circle is 94.985 ft^2.

EXPLANATION:

A = 1/4 x pi x diameter^2
A = 1/4 x 3.14 x 11^2
A = 0.785 x 121
A = 94.985 ft^2

Answer:

A = 94.985 ft²

Step-by-step explanation:

The formula of an area of a circle:

[tex]A=\pi r^2[/tex]

r - radius

We have the diameter d = 11 ft. We know d = 2r. Therefore r= 11 : 2 = 5.5 ft.

Substitute:

[tex]A=\pi(5.5)^2=30.25\pi\ ft^2[/tex]

[tex]\pi\approx3.14\to A\approx(30.25)(3.14)=94.985\ ft^2[/tex]
