C. 2,291 square meters

Step-by-step explanation:

The formula for finding the area of a circle is A= pi x r^2.

You are given the radius and 22/7 for pi so you can plug that into the formula. You should get A = 22/7 x 27^2.

After doing the math, you should get 2,291 1/7 as the answer. Since the problem says estimate, you can round that to 2,291 square meters.

Use the formula for the surface area of a rectangular prism:

$\sf A=2(wl+hl+hw)$

Plug in what we know:

$\sf A=2((18\dfrac{1}{2})(5\dfrac{1}{3})+(4\dfrac{5}{6})(5\dfrac{1}{3})+(4\dfrac{5}{6})(18\dfrac{1}{2}))$

Multiply:

$\sf A=2((98\dfrac{2}{3})+(25\dfrac{7}{9})+(89\dfrac{5}{12}))$

Add:

$\sf A=2(213\dfrac{31}{36})$

Multiply:

$\boxed{\sf A=427\dfrac{13}{18}~ft^2}$
