Answer: 40b - 16</h3>
Work Shown:
4(10b-4)
4*10b - 4*4
40b - 16
I multiplied the outer term 4 by each term inside. Refer to the distribution property (aka distributive property).
I'm assuming a quarter-circle is exactly 1/4 of a circle. Thus if you have 4 congruent quarter-circles, that should mean they make a complete circle.
If that is the case, then we can find the area of the full circle using pi*r^2.
So the area of the circle is 5^2*pi or 25pi.
To find the area of the shaded region, we subtract the area of the circle from the area of the square.
The area of the square is 10^2 or 100.
So the area of the shaded region is 100 - 25pi.
My calculator says that equals roughly 21.46
Answer:
D
Step-by-step explanation:
Counting from 28 to 44, that is more than 27 miles
28, 31, 32, 33, 35, 39, 42, 43, 44
That is 9 ran more than 27 miles
The answer is C
1+1=2
2+2=4
4+3=7
1+4=11
11+5=16
16+6=22
22+7=29.....
