Answer:
The area of the shaded region is 17.4 square meters.
Step-by-step explanation:
Since the shaded region in the center equals the remainders of a circle, the area of a square equals its side squared, and the area of a circle equals π times the radius squared, for To determine the area of the shaded region, the following calculations should be performed:
(9 ^ 2) - (π x (9/2) ^ 2) = X
81 - (π x 4.5 ^ 2) = X
81 - (3.141 x 4.5 ^ 2) = X
81 - 3.141 x 20.25 = X
81 - 63.6 = X
17.4 = X
Thus, the area of the shaded region is 17.4 square meters.
It’s 20% because 10/10 would be 100% and 1/10 would be 10%
Step-by-step explanation:

Because the lines are parallel,
The width of that rhombus, or parallelogram.
If you conutined that line, they will never ever touch.
That is the meaning of parallel, and why it is a parallelogram.
Answer:
18. 20,000.
19. 0
7. 1
11. 101
Step-by-step explanation:
18. I think is stays the same, because an integer is a number that is not a fraction. So still 20,000.
19. Sea level is at zero altitude. So answer is 0.
7. |17-16| = |1| = 1. The lines around it are called absolute value signs and mean to make the answer positive.
11. |-101| = 101. As said before the lines mean to make the inside part positive.
