<u><em>The complete question is</em></u>
A circle with a radius of 3 cm sits inside of a circle with a radius of 5 cm. What is the area of the Shaded Region?
The shaded region is the area outside the smaller circle and inside the larger circle
we know that
The area of the shaded region is equal to subtract the area of the smaller circle from the area of the larger circle
Remember that
The area of the circle is equal to
so
The area of the shaded region is
![A=\pi [r_1^2-r_2^2]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5Br_1%5E2-r_2%5E2%5D)
where
substitute
![A=\pi [5^2-3^2]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5B5%5E2-3%5E2%5D)
![A=\pi [16]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5B16%5D)
assume
substitute
Answer:
Step-by-step explanation:
d + q = 94.....d = 94 - q
0.10d + 0.25q = 19.30
0.10(94 - q) + 0.25q = 19.30
9.4 - 0.10q + 0.25q = 19.30
-0.10q + 0.25q = 19.30 - 9.40
0.15q = 9.90
q = 9.90/0.15
q = 66 <===== there are 66 quarters
d + q = 94
d + 66 = 94
d = 94 - 66
d = 28 <==== there are 28 dimes

Answer:
D is The correct Answer
Step-by-step explanation:
To find FDH and FDE you first need to solve GDH.
Here’s how to set up GDH.
8x-1=6x+15
Subtract 6x from both sides so that it cancels out.
2x-1=15
Add 1 to both sides so that it cancels out.
2x=16
Divide by 2z
x=8
Plug in.
GDH: 8(8)-1+6(8)+15=78
FDH: 122+78= 200
FDE: 122+15=137
