Answer:

81.12 cm²

Step-by-step explanation:

The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.

(3.14 * 4²)/2 + (14 * 8)/2 <em>(Work the operations in parentheses first.)</em>

(3.14 * 16)/2 + 112/2

50.24/2 + 112/2 (<em>Divide 50.24 by 2. Do the same for 112.)</em>

25.12 + 56 (<em>Add 25.12 & 56.)</em>

81.12 cm²

The area of the figure is 81.12 cm².

The vector equation of the line is:

\vec l = \vec P + t \cdot \vec A

\vec l = (-4, 11) + t\cdot (-3,8)

The parametric equations of the line are:

x = -4 - 3\cdot t and y = 11 + 8\cdot t
