The volume of the shaded portion of the cylinder help??????????????
Answer:
56.52mm²
Step-by-step explanation:
Based on observation, sum of diameters of small circles = diameter of the big circle.
In question, diameter of big circle = 12 mm.
And radius of big circle = 12mm/2 = 6mm
Let the diameter of each small circle be '2a'. So, radius of each small = 2a/2 = a.
=> 2a + 2a = 12mm
=> 4a = 12mm
=> a = 3mm
=> radius of each small circle = 3mm
Area of big circle = πr²
= (3.14)(6mm)²
= 113.04 mm²
Area covered by 2 small circles is: 2 * area of 1 one circle.
=> 2 * π(3mm)² = 18π mm²
=> 56.52 mm²
Shaded area = total area - area of 2 circles = 113.04 - 56.52 mm² = 56.52 mm²

What is the GCF of 81 and 72?
Answer:
9
Step-by-step explanation:
81= 1,3,9,27,81
72= 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36,72
9 is the most common so GCF will be 9.
Answer:
See below.
Step-by-step explanation:
81 - 1,3,9,27,81
72 - 1,2,3,4,6,8,9,12,18,24,36,72

5) A cellphone company charges a monthly fee of $34.00, plus $0.05 per text message. If you have at most $52 to spend, how many text messages can you send?
Answer:
At most you can send 360 text messages while spending at most $52.
Step-by-step explanation:
Let x = money per text message
34.00 + 0.05x ≤ 52
-34.00 -34.00
[tex]\frac{ 0.05x}{ 0.05}[/tex] ≤ [tex]\frac{18}{0.05}[/tex] = 360
So, at most you can send 360 text messages while spending at most $52.
Answer:
360

Identify the statement(s) that are both biconditional and false. Three points are not in the same plane if and only if exactly one line passes through them. Exactly one line passes through three points if the points are in an infinite number of planes. an infinite number of planes pass through the same three points if and only if the points are not on the same line. three points on the same line if and only if exactly one plane passes through them.
Answer:
Step-by-step explanation:
1) Three points are not in the same plane if and only if exactly one line passes through them.
It is biconditional and false because more than one plane can pass through three points
2)Exactly one line passes through three points if the points are in an infinite number of planes.
It is biconditional and true because three points on same line will be in more than one plane and if they are not in the same plane then connect them and it will form a triangle which is in only one plane
3). an infinite number of planes pass through the same three points if and only if the points are not on the same line.
It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them
4). three points on the same line if and only if exactly one plane passes through them.
It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them
what is the simplest form of - 1 5/12
Answer:

what is 22.8333333333 as a fraction?
Answer:
22 83/100
Step-by-step explanation:
22 is a whole number, while .8333 is continues you have to round it to .83. .83 is in the hundredths place so it would be 83/110. So in the end you'll have 22 83/100
Answer: I’m assuming this is supposed to repeat because that’s ridiculous if it isn’t. The answer is 22 5/6

Answer:
[tex]m = \frac{-1}{6}[/tex]
Step-by-step explanation:
You are solving for the slope (m). Use the following equation:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1 , y_1) =(-2 , 1)\\(x_2 , y_2) = (4 , 0)[/tex]
Plug in the corresponding numbers to the corresponding terms:
m = [tex]\frac{0 - 1}{4 - (-2)}[/tex]
[tex]m = \frac{-1}{4 + 2} \\m = \frac{-1}{6}[/tex]
[tex]m = \frac{-1}{6}[/tex] is your answer.

A rectangular piece of cheese is 9 centimeters long is 5 centimeters wide. What is the perimeter
Solution:
We know that:
Perimeter of rectangle = 2L + 2BGiven:
L = 9 cmW = 5 cmSubstitute the values into the expression to find the perimeter.
Perimeter of rectangle = 2L + 2B=> 2(9) + 2(5)=> 18 + 10=> 28 cmAnswer: 28cm
Step-by-step explanation:
The perimeter formula for a rectangle = 2(l + w); where:
length = 9cm
width = 5cm
P = 2(l + w)
= 2(9 + 5)
= 18 + 10
= 28cm
Therefore, the perimeter of the cheese is 28cm
26 - 44 : 11 - 5*2- 2*(14:7) =
Answer: 4
Step-by-step explanation:
Follow the PEMDAS so the first thing you do is 14:7 which is 2. then you do the division and multiplication so the 44:11 is 4, 5*2 is 10, and 2*2 is 4. The next thing you do is addition and subtraction. 26-4-4-10-4 is 4. So, the answer is 4.
