Calculate the perimeter of the shape below
Answers
Answer: The answer is C ≈ 18.85 meters.
Step-by-step explanation: The formula that you need is...
2 × π (pi or approximately 3.14) × r (which is the radius)
In this case, your radius is 3, so you solve by 2 × π (pi or approximately 3.14) × 3 which equals 18.8495559215 but you round to your nearest hundredth which gets you to have 18.85 meters as your answer! I hope this helps!

The base of a regular pyramid is a hexagon

a
What is the area of the base of the pyramid?
Answers
Answer:
Below in bold.
Step-by-step explanation:
The hexagon is made up of 6 equilateral triangles.
So the Base = 12 cm.
Height a = 12 cos 30 = 10.392 cm
So area of 1 triangle = 1/2 * 12 * 10.392 cm^2
- and total area = 6 * 1/2 * 12 * 10.392
= 36 * 10.392
= 374.11 cm^2 to the nearest hundredth.

If triangle RST and triangle XYZ are similar, which of these equations must be true?
Answers
Answer: A
Step-by-step explanation:
If they are similar, that means the proportions for corresponding sides will be the same.
I personally ignore the picture and use the labels of "triangle RST and triangle XYZ" that the problem gives because the XYZ picture is not lined up with the similarity it has with RST.
(A) says that side ST is corresponding with side YZ,
[] Triangle RST and triangle XYZ
-> Correct
(A) also says that side RT is corresponding with size XZ,
[] Triangle RST and triangle XYZ
-> Correct
This means that option A is the correct answer.

Step-by-step explanation:

B)The enlarged side shown in the problem statement is twice as long as the nearest parallel side of the rhombus. The scale factor is the ratio of the enlarged side length to the original side length: 2 : 1. The scale factor is 2.

Additional comment
There are several ways you can determine the scale factor. The endpoints of the image side are twice as far from the center of the rhombus as the original rhombus vertices. (The original extends 1 unit left, for example, while the enlargement is 2 units left.)
The length of a side of the original (blue) rhombus is the diagonal of a 1×2 rectangle on the grid. The drawn side of the image is two such lengths.

Answer:
1/27
Step-by-step explanation:
Okay first, calm down. Math is always hard when your stressed.
First step is to elimate b and write the equation in terms of a. So rearrange a-b=3 to b=a-3. Substitue that into the equation. Now you have :
27^1/3(a-3)
---------------
9^1/2(a)
Now rewrite the equation in terms of 3, you do this by realizing that 9 is simply 3^2 and 27 is simply 3^3. This gives you
3^(a-3)
---------
3^a
Now you use the laws of powers, and you get 3^-3, which is essentially 1/27.

Answers
Answer:
Step-by-step explanation:
The only way I can solve this is by assuming the letter on the far left is a B. If that is the case, <BAC and <EAC are supplementary.
Ignore the line going from C to D and look at the angle that is left. <EAC is out in the open. What happens is that <EAC and <BAC share the same starting poing which is A.
Each of the angles divide the diameter in two. The construction makes a total angle of 180 degrees which makes them supplementray.
<BAC + <EAC = 180o
<EAC = 31 degrees Given. Substitute that value into the equation above.
<BAC + 31 = 180 Subtract 31 from both sides.
<BAC +31-31 = 180 - 31 Combine
<BAC = 149

Total distanceLuke ( 4,10)
Nick (-8, -2)
Serena (4, -14)
Hence:
Distance between two points=√(x2-x1)²+ (y2-y1)²
Distance between Luke and Nick=√ (-8, -4)²+ ( -2-10)²
Distance between Luke and Nick=√288
Distance between Luke and Nick=16.97 feet
Distance between Luke and Serena=10-(-14)
Distance between Luke and Serena=24
Distance between Nick and Serena=√ (-8, -4)²+ ( -2+14)²
Distance between Nick and Serena=√ 288
