Three hundred nine thousand seventeen.
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.

Probability for a randomly chosen person is either a football player or a basketball player
=Prob for football player + Prob for basketball player -Prob for both
=

128*.69=88.32-8.83
128+8.83=136.83
Answer choice B is the answer.
