Step 1: Identify the shapes and their dimensions in the given figure.
The height of the triangle is 4 units ($$h = 4$$).
The figure consists of a semicircle and a right triangle. The diameter of the semicircle is also the base of the triangle.
Step 2: Calculate the area of the semicircle.
A_{semicircle} = frac{1}{2}pi (3)^2 = frac{1}{2}pi 9 = 4.5pi
Plugging in the values, we get:
Final Answer
The area of the shaded region is (4.5pi) - 12 square units, or approximately 1.57 square units when rounded to two decimal places.
