Answer: 376.8 cm^2
Step-by-step explanation:
The formula for the surface area of a cylinder is A = 2prh +2pr^2
When:
A = surface areap = value of pi (3.14 in this case)r = radius (= 1/2 diameter)h = heightWhen we substitute our values, we get the equation
A = 2(3.14)(4)(11) + 2(3.14)(4^2)
Now, we just multiply, square, and add our numbers to find A
A = 2(3.14)(4)(11) + 2(3.14)(4^2)
A = 2(3.14)(44) + 2(3.14)(16)
A = (6.28)(44) + (6.28)(16)
A = 276.32 + 100.48
A = 376.80
Because the hundredths place is a 0, we don't need to round.
A = 376.8
The unit is in centimeters. Area, and surface area by extent, are written in cm^2 (centimeters squared)
A = 376. 8 cm^2
Final answer: A = 376.8 cm^2
376.8 cm^2 might be wrong

What is the scale factor from figure A to figure B?
Answers
Answer:
1/3
Step-by-step explanation:
Figure A is
-the initial one and
-is bigger
so the scale factor is less then 1 and the figure A was shrunk to figure B
If we compare the sides of the triangles we see that the green triangle was shrunk by a k= 1/3 factor into the blue triangle.
Blue triangle is 3 times smaller than green triangle.

Carly placed 50 marbles in a bag. Fifteen of the marbles are pink, 8 marbles are black,
2 marbles are green, 18 marbles are clear, and 7 marbles are striped. Click and drag
the letters onto the probability scale to order the likelihood that the event will happen.
Answers
When you go into this problem, you want to figure out your marble ammount to 50 so in this case we will say C for color and 50 for the total ammount of marbles.
We know 15 are pink, 8 are black, 2 are green, 18 are clear, and 7 are striped
15P/50
8B/50
2G/50
18C/50
7S/50 for a total of 50 marbles
Now we use the chart to decide our awnsers
A. We know our propability of drawing a green and clear is 20/50 which if we simplify is a 2/5 ratio. If We put this in perspective 2/5 is rare and is unlikley to even.
B. We know a striped marble is 18/50 or 1.8/5 ratio which is mainly unlikely
C. We have 23/50 marbles that are black and pink, our propability is about 2.3/5 and gives us an even chance to get one of these
D. We know we have 33/50 marbles that are pink and clear and gives us a 3.3/5 chance of getting one of these and gives us an even to likely chance of getting one of these.
E. If we have a total of 17 marbles in these 3 colors, we have a 1.7/5 chance of getting one of these and is probably impossible to unlikey.
In a bag, there are 100 same-sized chips labeled 1 through 100. If one chip is selected without looking, order the probabilities of the events below by placing the event with the greatest probability on top.
Answers
Answer:
a: 89/100
b: 19/100
c: 28/100
Step-by-step explanation:
for a, take every number greater than 10. there are 100 chips, so 89/100 chips are greater than 10. do this for each of the other questions.
The order for the probabilities of the events by placing the event with the greatest probability on top is
1. The label is a number between 30 and 60
2. The label is a number less than 20
3. The label is a number greater than 10
How did we arrive at this order?Below are the correct order of the probabilities from greatest to least:
1. The label is a number between 30 and 60
2. The label is a number less than 20
3. The label is a number greater than 10
The reason for this order is that there are 31 chips with labels between 30 and 60, 19 chips with labels less than 20, and 90 chips with labels greater than 10.
Therefore, the correct answer is as given above.

Answer: 59.3 feet
Step-by-step explanation: we will multiply 11.711.77 ✖ 2.8✖1.8 equal 59.3208 so estimate the 2 can't give something to the 3 so 559.3 , hope my answer is correct
Explanation:
Since you are finding the depth your formula will look like this
11.77= 2.8 x 1.8 x d
(d stands for depth since we don’t know the value)
To solve it you multiply 2.8 and 1.8 which equals 5.04
So now your equation looks like this
11.77= 5.04 x d
Next you divide 11.77 by 5.04 and get
2.33531746
This rounds to 2 so the answer is 2.

Angle AFC is supplementary to angle CFE. Supplementary angles always equal 180 degrees. (180-120=60)
Answer:
1. 60
2. 120
3.30
Step-by-step explanation:
(Yes I know they aren't labeled one and two but I'll go in order from the questions)
1. It is 60, because it is an equilateral triangle so all angles are equal. 180/3=60.
2. There are two ways you can solve this problem. The first is using the vertical angle theorem. That makes it 120. Or, you can add all the angles you have already and remove it from 360.
360-120-60-60=120.
(you can tell it is not 60 because it is larger than a right angle in the picture)
3.x=30.The right angle is 90, and there is a 60 degree angle, so 90-60=30

find the area of the circle. Use 3.14 for π. do NOT round your answer.
Answers
Diameter = 2r so 11 = 2r
r=5.5
A = 3.14*(5.5)^2
A= 3.14* 30.25
A= 94.985
Answer:
A≈95.03
Step-by-step explanation:
The Formula for an area of a circle is A=πr2
Becuase the Radius is half of the diameter then we would divide 11 by 2
which is 5.5
plug it in the equation
A =π (5.5)squared
square 5.5
A=30.25π
A= 95.0331777711

this would make the equation the following:

first, multiple 1/2 by 25 to get 12.5
the equation should now look like this:
100=12.5h
since we are looking for what h is, we must isolate h by dividing both sides of the equation by 12.5
now the equation should look like this:
8=h
the answer is 8 yds

Solve the expression 6 x one sixth + 11 x 2
Answers
Step-by-step explanation:
6 x 1/6= 1
11 x 2= 22
22+1= 23
Since multiplication comes before addition in PEMDAS, you’ll need to do multiplication first. The first multiplication in this expression is 6 x 1/6 which can also be written as 6/1 x 1/6
6/1 x 1/6 = 1
The second multiplication in this equation is 11 x 2
11 x 2 = 22
Now you can add both of the numbers and you’d get 23 :)
1 + 22 = 23

Miguel draws a square on a coordinate plane. One vertex is located at (5,4). The length of each side is 3 units. Circle the letter by all the ordered pairs that could be another vertex.
A. (5,1)
B. (5,7)
C. (7,8)
D. (2,6)
E. (2,1)
Answers
Answer:
A, B, and E.
Step-by-step explanation:
We know that one vertex is at (5, 4), and each side of our square is 3 units long.
Then the distance between the known vertex and another vertex is 3 units (if those vertexes are connected by a side of the square) or (√2)*3 units (if those vertexes are connected by the diagonal of the square).
Also remember that the distance between two points (a, b) and (b, c) is:
distance = √( (a - c)^2 + (b - d)^2)
So we need to find the distance between our point and all the ones given in the options:
A) the distance between (5, 4) and (5, 1) is:
distance = √( (5 - 5)^2 + (4 - 1)^2) = 3
Then point (5, 1) can be a vertex.
B) The distance between (5, 4) and (5, 7) is:
distance = √( (5 - 5)^2 + (4 - 7)^2) = 3
Then (5, 7) can be a vertex.
C) The distance between (5, 4) and (7, 8) is:
distance = √( (5 - 7)^2 + (4 - 8)^2) = √( 2^2 + 4^2) = √20
Point (7, 8) can not be a vertex.
D) The distance between (5, 4) and (2, 6) is:
distance = √( (5 - 2)^2 + (4 - 6)^2) = √( 3^2 + 2^2) = √13
Point (2, 6) can not be a vertex.
E) The distance between (5, 4) and (2, 1) is:
distance = √( (5 - 2)^2 + (4 - 1)^2) = √( 3^2 + 3^2) = √18 = √(2*9) = √2*√9 = √2*3
Then point (2, 1) can be a vertex.

A triangle is 180 degrees and you have a 30 and 50 angle so the third angle should equal 100. so the answer should be 45 and here's why
Step-by-step explanation:
Subtract 10 from both sides
2x+10=100
2x+10-10=100-10
Simplify
Subtract the numbers
2x=90
Divide both sides by the same factor
2x=90
2x/2 = 90/2
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
x=45
Solution
45
