The area of a circle is calculated using the formula A = πr², where A represents the area, π is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

In this case, the radius is 12 feet. Plugging this value into the formula gives:

A = π(12 feet)²

A = π(144 square feet)

A = 144π square feet.

This indicates that the correct answer is indeed the area expressed as 144π square feet.

The other choices reflect a misunderstanding of the units or the formula. The choice stating 144 square feet does not account for π and is only the radius squared without any further calculation. The option indicating 144π cubic feet misapplies the area formula, mixing area and volume units improperly. Lastly, the assertion of 288 square feet does not utilize the π in its computation for the area of a circle. Thus, identifying the area as 144π square feet accurately represents the mathematical calculation and concept involved.
