• Surface area of a cylinder = 2πr(r + h) sq. units.
In the above diagram,
Radius (r) of the cylinder = 13 cm.
Height (h) of the cylinder = 39 cm.
• Taking value of π = 3.14Hence, Surface area of the cylinder = 2 × 3.14 × 13(13 + 39)
Surface area of the cylinder = (81.64 × 52) cm²
Surface area of the cylinder = 4245.28 cm²
The surface area of the cylinder is 4245.28 cm². [Answer]
Step-by-step explanation:
Solution:
• Surface area of a cylinder = 2πr(r + h) sq. units.
In the above diagram,
Radius (r) of the cylinder = 13 cm.
Height (h) of the cylinder = 39 cm. Taking value of π = 3.14
Hence, Surface area of the cylinder = 2 x 3.14 ×
13(13 +39)
Surface area of the cylinder = (81.64 x 52) cm²
Surface area of the cylinder = 4245.28 cm²
The surface area of the cylinder is 4245.28 cm².

Answers
Answer:
1. The mean for Group A is less than the mean for Group B
2. The median for Group A is less than the median for Group B.
3. The mode for Group A is less than the mode for Group B.
Step-by-step explanation:
1. To find the mean for Group A, you use the formula: Total sum/Total frequency.
To find the total sum, you multiply the frequency(how many times the given number is repeated) with the given numbers.
0 × 0 = 0
1 × 5 = 5
2 × 4 = 8
3 × 1 = 3
4 × 0 = 0
5 × 0 = 0
Total Sum: 5 + 8 + 3 = 16
Total frequency: 5 + 4+ 1 = 10
[tex]\frac{16}{10}[/tex] = 1.6
To find the mean for Group B, you repeat everything above.
0 × 0 = 0
1 × 3 = 3
2 × 2 = 4
3 × 4 = 12
4 × 0 = 0
5 × 1 = 5
Total Sum: 3 + 4 + 12 + 5 = 24
Total frequency: 3 + 2 + 4 + 1 = 10
[tex]\frac{24}{10}[/tex] = 2.4
2. I can't explain it but I'm certain that it is correct.
3. The most repeated number for Group A is 1, it is repeated 5 times, while the most repeated number in Group B is 3, it is repeated 4 times.

Vinnie is searchng online for airline tickets. Two weks ago, the cost to fly from Denver to Boston was $250. Now the cost is $365.
1. What is the percent increase?
Answer: The percent increase ofthe airline ticket is %. (Just write the number, not the % sign)
2. What would be the percent increse if the airline charges an additonal $50 baggage fee withthe new ticket price?
Answer: The percent increase of he airline ticket with the baggage fee is %
Answers
I'll do the first one to get you started.
A = old price = 250
B = new price = 365
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (365 - 250)/250 ] * 100%
C = (115/250) * 100%
C = 0.46 * 100%
C = 46% increase
We have an increase because the resulting C value is positive. If C were negative, then we'd have a percent decrease.

Answer:
25%
Step-by-step explanation:
This is the answer because there are 4 different types of cards that can be chosen, the amount of trials is insignificant in this question. Since there are 4 types, there is a 1/4 chance of picking a club, another way to put this is 25%, thus giving your answer!

Julie has a jewelry box shaped like a cube. The volume of the jewelry box is v cubic inches. Part A: Write an expression that represents the edge length of Julie’s jewelry box in inches.
Answers
Answer:
∛v
Step-by-step explanation:
As you already should know, volume is measured by hwl (height • width • length), we know the equation we'd use here would be:
___ x ___ x ___ = v in³
If this was area, we would have ___ x ___ = v in², and it would be easy to find each blank. You would just find the square root of "v", making your answer √v.
When you have 3 things multiplied by each other (that are exactly the same, which is the situation here since this is a cube), you will want to find ∛x (if x is our unknown variable). This means that we are finding ONE-THIRD of the number ... sort of. So if x was equal to 8, then ∛x = 2, because 2 x 2 x 2 = 8.
Thus, x = v, and since we don't know the actual number, we will keep it as a square root, so the answer to your question is ∛v.

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 6 rows of the same length, he
has 7 chairs left over. If he arranges the chairs in 4 rows of that same length, he has 13 left over. How many
chairs does Liam have?
Answers
This sets up a problem of:
6x + 7 = 4x + 13
7 and 13 being the leftover chairs and 6 and 4 being the rows. Let’s solve for x.
x = 3
Knowing this, we plug in x for one of the equations
6(3) + 7
18 + 7
25
Liam has 25 chairs.
