The area of the circle is 81 π units². It is divided into 6 equal parts. What is the perimeter of the shaded region in terms of π?
I attached a diagram as well.
I'd also appreciate anyone who can help me, as I am in need of it.
Thank you.
Answers
(pi)r^2
(pi)r^2 = (pi) 81
r^2 = 81
r = 9
Perimeter of a circle:
2(pi)r
[2(pi)9]:3 = (18pi):3 = 6pi [the two small arcs]
9 = 2.87pi
2.87pi x 4 = 11.5pi
Perimeter of shaded area:
11.5pi + 6pi = 17.5pi

Part B
What is the total number of biscuits that can be made using one box of the biscuit mix?
Show your work or explain your answer.
Part C
What is the cost, in dollars and/ or cents, per biscuit? Show your work or explain your answer.
Answers
Answer:
Part A: Total number of cups of biscuit mix in one box is 18 cups.
Part B: You can make 54 biscuits using one box of biscuit mix.
Part C: 0.12 $ per biscuit.
Step-by-step explanation:
Part A: 72 x 1/4
Part B: In the chart, it shows us a pattern. The number of cups required times 3 = the number of biscuits or vice versa. So the number of cups required is 18 and 18 x 3 is 54 so we can make 54 biscuits.
Part C: 6.48$/54

(a) 5
(b) 3rd quartile
(c) 2nd quartile
Step-by-step explanation:
There are four quartiles in a box plot (or box and whisker plot).
The 1st is from 5 to 13
The 2nd is from 13 to 35
The 3rd is from 35 to 40
The 4th is from 40 to 48
(a) The lowest that this box plot goes is 5 (between the 4 and 6)
(b) 3rd quartile — we can see that the left and right borders are close together, meaning that the data values for this quartile are close together, and therefore concentrated
(c) 2nd quartile — we can see that this quartile is the widest, and therefore the data values are spread out

because…
2x-26+7x+8=180
9x-18=180
9x=198
x=22
Answer:
[tex]\Longrightarrow:\boxed{\sf{x=22}}[/tex]
Step-by-step explanation:
To find the value of x, isolate it on one side of the equation.
Given:
[tex]\Longrightarrow: \sf{m: (2x-26)}\\\\\\\Longrightarrow: \sf{n: (7x+8)}[/tex]
[tex]\Longrightarrow: \sf{2x-26+7x+8=180}[/tex]
First, combine like terms.
[tex]\Longrightarrow: \sf{2x+7x-26+8=180}[/tex]
Add the numbers from left to right.
2x+7x=9x
[tex]\Longrightarrow: \sf{9x-26+8=180}[/tex]
-26+8=-18
[tex]\Longrightarrow: \sf{9x-18=180}[/tex]
Add by 18 from both sides.
[tex]\Longrightarrow: \sf{9x-18+18=180+18}[/tex]
Solve.
Add these numbers from left to right.
180+18=198
[tex]\Longrightarrow: \sf{9x=198}[/tex]
Divide by 9 from both sides.
[tex]\Longrightarrow:\sf{\dfrac{9x}{9}=\dfrac{198}{9}}[/tex]
Solve.
Divide the numbers from left to right.
198/9=22
[tex]\Longrightarrow: \boxed{\sf{x=22}}[/tex]
Therefore, the correct answer is x=22.I hope this helps. Let me know if you have any questions.

PLS HELP (answer isn't 1384.74 lol)
Answers
Answer:
1385mm squared
Step-by-step explanation:
Area of Circle formula: A = pi r^2
You need to divide 42mm by 2 since that is a diameter.
*Half of the diameter is the radius*
42/2 = 21
Now, do 3.14 multiplied by 21 to the power of 2.
Formula: A = 3.14 x 21^2
Do 21^2 first.
That shall be 441
Now do 3.14 x 441
1,384.74mm - That is your exact answer.
The directions tell you to round it to the nearest whole number
THAT IS 1385mm squared
