Final answer:
The area of the semicircle with a radius of 16.5 yd is approximately 3419.5 yd².
Step-by-step explanation:
To find the area of the semicircle, we can use the formula for the area of a circle: A = πr². Given that the radius of the semicircle is 16.5 yd, we can substitute this value into the formula: A = π(16.5)^2.
Using the value of π as 3.14, we can calculate the area of the semicircle as follows: A = 3.14 * (16.5)^2. Evaluating this expression gives us the area of the semicircle as approximately 3419.5 yd². Therefore, the correct answer is A. 3419.5 yd².
