Answer:
25.9666 m
Step-by-step explanation:
The 4 arches combine to for a circle, so then you can find the area of the shaded region by subtracting the area of the square from the area of the circle.
The formula for area of a circle is A=r^2
Since the radius of the circle would be 11/2 or 5.5, the area if the circle would be x 5.5^2. This equals 95.0334.
The area of the square would be 11 x 11 = 121.
The 121-95.0334= 25.9666 m
Answer: Choice D
Step-by-step explanation:
cos(32) = 0.8480480962
cos(58) = 0.5299192642
cos(68) = 0.3746065934
sin(32) = 0.5299192642
sin(58) = 0.8480480962
Cos(58) = sin(32)
Cos(32) = sin(58)

Step-by-step explanation:
A "sum" means that we will be using addition, while a "difference" indicates subtraction. Anytime we have two unknown numbers we generally use "x" and "y".
