Answer:
Ok so what you should is first find the area for both of the circle
[tex]Area = \pi r^2\\[/tex]
Big circle
you are given the radius which 14mm
[tex]3,14(14)^2 = 615.44 mm^2[/tex]
Small circle
you are given the diameter of the small circle which 14mm
radius = diameter/2
14/2=7mm
[tex]3.14(7)^2 = 153,86mm^2[/tex]
Shaded area means the difference between the 2 areas, in my opinion
so you do 615.44 - 153.86 = 461.58 mm^2
Hope that answers your question

Answers
Answer:
The answer is A
Step-by-step explanation: BIG BRAIN
The equation that will tell us the measure of the additional angle, a, that Nuha needs to push the door before she can get out is D: 160 - 40 - a.
To determine the equation that will give us the measure of the additional angle, a, that Nuha needs to push the door before she can get out, we can break down the information provided:
1. The door needs to rotate 160° for Nuha to pass through.
2. The wind pushed the door 40°.
To find the additional angle that Nuha needs to push the door, we can subtract the angle already rotated (40°) and the angle she needs to pass through (160°) from the total rotation angle:
Total rotation angle = Angle already rotated + Angle Nuha needs to push + Additional angle Nuha needs to push
Based on this equation, we can eliminate options A, B, and C since they do not accurately represent the situation.
The correct equation is option D: 160 - 40 - a. This equation represents subtracting the angle already rotated (40°) and the angle Nuha needs to pass through (160°) from the total rotation angle, leaving the additional angle (a) that Nuha needs to push the door.

The complete question:
Nuha is going through a revolving door that needs to rotate 160° to allow her to pass through. The wind pushed the door around 40°. Nuha needs to push it the rest of the way.
Which equation will tell us the measure of the additional angle, a, that Nuha needs to push the door before she can get out?
Choose 1 answer:
A: 160+40= a
B: 40 x 2 = a
C: 160 ÷ 40 = a

We are finding hypotenuse but first we find the length of all sides of the two squares to find the two sides of the triangle then we find hypotenuse.
Answer:
Step-by-step explanation:
OH you have to find what the lengths of the sides of the squares are, It would have been easier if they made the area 36 because that is a squared number and easy to find but because they didn't you just have to put 32 into a square root and the output would be 5.6.
why are we doing this? because 5.6*5.6=32, the area of the square. that means that 5.6 and 5.6 can be plugged into the A^2+B^2=C^2 equation 5.6^2+5.6^2=c^2 the missing side.
=984 should be the missing side but do the work yourself because that number that I came up with doesn't look right.

C. 69°
D. 70°
Answers
Answer:
C. 69 (nice)
Step-by-step explanation:
Sine: Opposite side over hypotenuse
Cosine: Adjacent side over hypotenuse
Tangent: Opposite side over adjacent side
Respective to angle O, we are given the adjacent side, 5, and the hypotenuse 14, so we can use cosine.
cos(O)=5/14
O=arcsin(5/14)≈69.0752
The answer is 69.

What is the surface area of the rectangular prism?
Answers
Answer:
348 in.² is the answer.
Step-by-step explanation:
To find our answer we will multiply each number by each other.
6 x 8 = 48
6 x 9 = 54
8 x 9 = 72
Now we have our numbers 48, 54, and 72, we will multiply each one by 2.
48 x 2 = 96
54 x 2 = 108
72 x 2 = 144
For our final step we will add all these together to find our surface area. 96 + 108 + 144 = 348. Therefore, 248 in² is our answer.

Si un rombo tiene un lado con medida de 16 pulgadas. Cual es su perimetro . If a rhombus has a side measured 16 inches. What is its perimeter.
Answers
Answer:
64 inches or 64 pulgadas
Step-by-step explanation:
The formula for the perimeter of a rhombus is given as:
P = 4a
Where a = side length of the rhombus
From the above question, side length of the rhombus = 16 inches
Hence, Perimeter of the rhombus = 4 × 16 inches
= 64 inches
La fórmula para el perímetro de un rombo se da como:
P = 4a
Donde a = longitud del lado del rombo
De la pregunta anterior, la longitud del lado del rombo = 16 pulgadas
Por lo tanto, perímetro del rombo = 4 × 16 pulgadas
= 64 pulgadas
