Preface: We know that the radius of the cylinder is 2 inches and the height is 7 inches. Using the surface area formula (for a cylindrical figure), which has been provided below, we can, through calculations, figure out that the surface area of the cylinder is...
Formula: A = 2π × r × h + 2πr2= 2πr (h + r)
Variables: The "A" is the answer; "R" represents the radius and the "H" is the variable for the height of the cylinder. For the purpose of this question, we'll substitute 3.14 for pi (π).
Surface Area ≈ 113.1, or if you want the exact solution: 113.09734.

Answer:
1st Q- B
2nd Q- A
Step-by-step explanation:
1st Q:
n²<220<(n+1)²
n²<220<(n²+2n+1)
we can plug in the values in the answers and see which one satisfies the inequality:
when n=13 --> 13²<220<(13²+2*13+1) => 169<220<196 (this one does not work)
when n=14 --> 14²<220<(14²+2*14+1) => 196<220<225 (this one works)
when n=15 --> 15²<220<(15²+2*15+1) => 225<220<256 (this one does not work)
when n=16 --> 16²<220<(16²+2*16+1) => 256<220<289 (this one does not work)
so the answer is B
2nd Q:
A
(see the attachment below for explanation)
If p=1 and q=4, evaluate the following expression:4q−p/p+q
Answer:
19
Step-by-step explanation:
This was done the normal way of multiplying and dividing first:
If p=1 and q=4, evaluate the following expression:
4q − p/p + q = ?
4(4) - 1/1 + 4 = 16 - 1 + 4 = 19
If you wanted to do the addition and subtraction first, the equation would have been:
(4q - p)/(p + q) = ?
(4(4) - 1)/(1 + 4) = 15/5 = 3
With the parentheses, the order of operations is done in the parentheses first.
Suppose you are a salesperson for Quark Computer Company. Each month you earn $500 plus one sixth of your sales. What amount must you sell this month to earn $3000?
Answer:
sales equal $15,000
Step-by-step explanation:
x = amount of sales
f(x) = 500 + 1/6x
3000 = 500 = x/6
2500 = x/6
x = 15,000

At the beginning of school you set-up a 4 digit pin to get into your My Payments Plus
account, however you have not used your account since you set it up and forgot the
number. You remember that the first number was a 4 and the second number was
either a 5, 6, or 7. You had no idea what the last two numbers were.
How many
different combinations are possible?
900 combinations
200 combinations
300 combinations
1200 combinations
Answer:
Step-by-step explanation:
The first number is one choice: 1
the second number is one of 3: 3
The last 2 digits can each be any one of the 10 digits from 0 to 9: 10 * 10
3*100 = 300
Not too many, but it will take you awhile to run through them.

Given:
In a parallelogram [tex]PRTV, VQ\perp PR,VS\perp RT[/tex].
To prove:
[tex]\dfrac{PQ}{ST}=\dfrac{PV}{VT}[/tex]
Solution:
It is given that [tex]VQ\perp PR,VS\perp RT[/tex], it means [tex]\angle PQV[/tex] and [tex]\angle TSV[/tex] are right angle triangles.
In triangle PQV and triangle TSV,
[tex]\angle PQV\cong \angle TSV[/tex] (Right angles)
[tex]\angle QPV\cong \angle STV[/tex] (Opposite angles of a parallelogram)
Two corresponding angles are congruent. So, by AA property of similarity, we get
[tex]\Delta PQV\sim \Delta TSV[/tex]
We know that the corresponding parts of similar triangles are proportional. So,
[tex]\dfrac{PQ}{TS}=\dfrac{PV}{TV}[/tex]
It can be rewritten as:
[tex]\dfrac{PQ}{ST}=\dfrac{PV}{VT}[/tex]
Hence proved.

What is the value of x?
9514 1404 393
Answer:
98
Step-by-step explanation:
The angle bisector divides the triangle proportionally. This means ...
VY/VT = KY/KT
VY = VT(KY/KT)
x = VY +KY = (KY(VT/KT) +KY) . . . . . use the expression for VY
x = KY(VT/KT +1) . . . . . . . . . . . . . . . factor out KY
x = (68)(57/129.2 +1) . . . . . . . . .. put in the numbers
x = 98

) A day’s sale at a book shop is represented in a pie chart with the following data. If the total sale at the end of the day is ₹ 1440, then how much was the contribution of Non Fiction books towards the sale? *
Rs 360
Rs. 230
Rs. 320
Non fiction has 80 degrees
Answer:
Rs. 320
Step-by-step explanation:
Contribution of Non Fiction books towards the sale = (degree of non fiction books / total degrees in a circle ) x 100
degree of non fiction books = 80
total degrees in a circle = 360
(80 / 360) x 1440 = Rs. 320
2 bottles of grape juice fill 8 glasses. How many glasses can be filled from
8 bottles of grape juice?
Answer:
32 glasses
Step-by-step explanation:
To solve this we will first find out how many glasses one bottle of grape juice can fill.
Equation:
8/2 = 4
This means one bottle of grape juice can fill four glasses. Now all we have to do is multiply 4 glasses of grape juice by the number of bottles.
Equation:
8 * 4 = 32
32 glasses

When 43,55 and 67 are divided by a certain number, the remainder is 7 in each case. Find the number?
Answer:
12
Step-by-step explanation:
First subtract 7 from 43, 55 and 67
43 - 7 = 36 ; 55 - 7 = 48 ; 67 - 7 = 60
Now find the GCF of 36 , 48 , 60
36 = 2 * 2 * 3 * 3
48 = 2 * 2 * *2*2 * 3
60 = 2 * 2 * 3 * 5
GCF = 2 * 2 * 3 = 12
The required number is 12
When you divide 43 by 12, the remainder is 7.
When you divide 55 by 12, the remainder is 7
When you divide 67 by 12, the remainder is 7

how do i find the diameter of a circle with only knowing the area?
Answer:
2 * (Area/pi)^(1/2) = diameter
Step-by-step explanation:
The equation for the area of a circle is A = pi * r^2
We can divide both sides by pi to get:
A/pi = r^2
Then take the square root of both sides to get:
(A/pi)^(1/2) = r
Then, since D = 2 * r, we can multiply both sides of the above equation by 2 to get:
2 * (A/pi)^(1/2) = 2 * r = D
Answer:
d=2[tex]\sqrt{a/\pi }[/tex]

Answer:
x = 16 and y = 116
Step-by-step explanation
For the trapezoid, the sum of the adjacent side is 180. Hence;
6x+20 + 4x = 180
10x + 20 = 180
10x = 180-20
10x = 160
x = 160/10
x = 16
Also, the sum of opposite side is 180, hence;
4(16)+ y = 180
64 + y = 180
y = 180 - 64
y = 116 degrees
hence x = 16 and y = 116
Solve 4x/3=8
X=__
Please and Thank you!
Answer:
x=8
Step-by-step explanation:
4x/4=8
Multiply both sides by 4
4*4x/4=8*4
Simplify;
4x=32
Divide both sides by 4
4x/4=32/4
Simplify;
x=8

Krystal made 8 quarts of soup on Monday 5 quarts of soup on Tuesday and 5 quarts of soup on Wednesday. If she serves each guest 1 cup of soup how many guests can she serve in all?
Answer:
To get the answer you need to add these together to find the total number of quarts she made.
8+5+5= 18 quarts of soup.
If everyone gets one cup, then 18 people are able to get soup.
The answer is 18 guests.
Step-by-step explanation:
Hope this helps!
Answer: 72 guests total
Step-by-step explanation: Convert quarts to cups to see how many total cups she has...
1 quart = 4 cups
so we find total quarts she cooked and multiply by 4 to find out how many total cups...
8+5+5=18
18x4=72
she made 72 total cups and each guest gets 1 cup
divide total cups by number of cups per guest...
72/1=72
