Answer:
A. 75.4m²
Step-by-step explanation:
The area of a circle is [tex]\pi r^{2}[/tex].
To find the area of the deck, you need find the radius, which is the diameter of the hot tub + 4.4 (because the added length to each side is 2.2), which adds up to 9.8. Then divide that by two to get 4.9, which is the radius. Then plug it into the equation.
Area of the circle: [tex]\pi (4.9)^{2} =75.43m^{2} \\[/tex]
