Answer:

$\displaystyle 415,5\:units^2 ≈ A$

Step-by-step explanation:

In the circumference, 27 represents the diameter, and the radius is <em>half</em><em> </em>the diameter, so take half of it to get 11,5. Then use it in the area formula:

$\displaystyle πr^2 \\ \\ π11,5^2 = 132,25π ≈ 415,4756284 ≈ 415,5$
