Answer:
76.93 cm
Step-by-step explanation:
Since the area of a circle is [tex]\pi r^{2}[/tex], where r is the radius, the area of a semicircle would be half of a circle's area, meaning [tex]\frac{1}{2} \pi r^{2}[/tex]. From the diagram, the semicircle has a diameter of 14cm, and the radius is half of the diameter so r = 14/2 = 7cm.
Plugging in the value for radius r, we get [tex]\frac{1}{2} \pi (7)^{2}[/tex] ≈ [tex]76.9690200129 cm[/tex].
So the right answer is 76.93 cm.
