Answer:
The area of the shaded portion of the figure is
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The shaded area is equal to the area of the square less the area not shaded.
There are 4 "not shaded" regions.
step 1
Find the area of square ABCD
The area of square is equal to

where
b is the length side of the square
we have

substitute

step 2
We can find the area of 2 "not shaded" regions by calculating the area of the square less two semi-circles (one circle):
The area of circle is equal to

The diameter of the circle is equal to the length side of the square
so
---> radius is half the diameter
substitute


Therefore, the area of 2 "not-shaded" regions is:

and the area of 4 "not-shaded" regions is:

step 3
Find the area of the shaded region
Remember that the area of the shaded region is the area of the square less 4 "not shaded" regions:
so
---> exact value
assume

substitute
Answer:
false because rounding it will not show the exact number
Answer: $5,744.61
Step-by-step explanation:
year 1 = -2,277
year 2 = -2026.53
year 3 = -1803.61
year 4 = -1605.21
year 5 = -1428.64
year 6 = -1271.49
year 7 = -1131.62
year 8 = -1007.17
year 9 = -896.36
year 10 = -797.76
year 11 = -710
you are subtracting 11% from each year.
