¿Cuál es el volumen máximo de agua que

¿cuál es la extensión del cerco de seguridad?
(considere П=3)
Answers
The length of the fence must be 618cm
The volume that it can hold is 1,909,620 cm³
How to find the volume and the length of the fence?First, the fence is just equal to the circumference of the cylinder, remember that the circumfernce of a circle of diameter D is:
C = П*D
Here we use П = 3, then:
C = П*206cm
C = 3*206cm = 618cm
Now the volume, for a cylinder of diameter D and height H, the volume is:
V = П*(D/2)²*H
Replacing the values that we know we will get:
V = 3*(206cm/2)²*60cm = 1,909,620 cm³

What is Surface Area?Surface area refers tο the tοtal area οf the οuter surface οf a three-dimensiοnal οbject. It is measured in square units, such as square inches οr square meters.
The fοrmula fοr the surface area οf a sphere is:

The diameter οf the dοg tοy is given as 3 inches. The radius, which is half οf the diameter, is therefοre:
r = 3/2 = 1.5 inches
Substituting this value intο the fοrmula fοr surface area, we get:
A = 4π(1.5)²
A = 4π(2.25)
A = 9π
Using a calculatοr tο apprοximate the value οf π tο 3.14, we get:

Demand for bikes has suddenly increased, and the market price has risen from $50 to $60.
In three to five sentences, explain how this change will affect profits.
Answers
Answer:
profits will increase so with that being said the supply of them dropped if demand increased getting bikes will be harder for competing business in the area and so therefore if you have 200 bikes and others have 50 bikes your gonna make way more profit and for the people with 50 bikes they will gain and lose profits because when they run out of bikes they have to buy more and they are more expensive because of the demand on them
Step-by-step explanation:
The explanation regarding the change of price that impact the profits should be explained below.
Impact on profit:The profit should rise when the supply should fall. In the case when I have 200 bikes while the other should have 50 bikes so here I make more profit however the other people will gain but the profit should be lost since the bikes should be out of the stock and at the same time they need to buy more that should be more expensive due to the demand.

An account grows at an annual interest rate of r , so it grows by a factor of x=1+r each year. The function A(x)=800x 4 +350x 3 +500x 2 +600x gives the amount in the account after 4 years when the growth factor is x . What is the total amount in the account if the interest rate for the account is 3% each year? How much money was put into the account at the beginning?
Answers
Given:
Annual interest rate = r%
Growth factor : x = 1 + r
The below function gives the amount in the account after 4 years when the growth factor is x .
\(A(x)=800x^4+350x^3+500x^2+600x\)
To find:
The total amount in the account if the interest rate for the account is 3% each year and initial amount.
Solution:
Rate of interest = 3% = 0.03
Growth factor : x = 1 + 0.03 = 1.03
We have,
\(A(x)=800x^4+350x^3+500x^2+600x\)
Substitute x=1.03 in the given function, to find the total amount in the account if the interest rate for the account is 3% each year.
\(A(1.03)=800(1.03)^4+350(1.03)^3+500(1.03)^2+600(1.03)\)
\(A(1.03)=800(1.12550881)+350(1.092727)+500(1.0609 )+618\)
\(A(1.03)=900.407048+382.45445+530.45+618\)
\(A(1.03)=2431.311498 \)
\(A(1.03)\approx 2431.31 \)
Therefore, the total amount in the account is 2431.31 if the interest rate for the account is 3% each year.
For initial amount the rate of interest is 0.
Growth factor : x = 1 + 0 = 1
Substitute x=0 in the given function to find the initial amount.
\(A(1)=800(1)^4+350(1)^3+500(1)^2+600(1)\)
\(A(1)=800+350+500+600\)
\(A(1)=2250\)
Therefore, 2250 was put into the account at the beginning.

Answer:
Ms. Long ordered a pizza with area 50.24 ft².
Step-by-step explanation:
Solution :Here, we have given that the radius of circular pizza is 4 ft.
So, finding the area of circular pizza by substituting the values in the formula :
\(\longrightarrow{\pmb{\sf{Area_{(Circle)} = \pi{r}^{2}}}}\)
\(\longrightarrow{\sf{Area_{(Pizza)} = 3.14{(4)}^{2}}}\)
\(\longrightarrow{\sf{Area_{(Pizza)} = \dfrac{314}{100} \times {(4 \times 4)}}}\)
\(\longrightarrow{\sf{Area_{(Pizza)} = \dfrac{314}{100} \times (16)}}\)
\(\longrightarrow{\sf{Area_{(Pizza)} = \dfrac{314}{100} \times 16}}\)
\(\longrightarrow{\sf{Area_{(Pizza)} = \dfrac{314 \times 16}{100}}}\)
\(\longrightarrow{\sf{Area_{(Pizza)} = \dfrac{5024}{100}}}\)
\(\longrightarrow{\sf{Area_{(Pizza)} = 50.24 }}\)
\(\star{\underline{\boxed{\sf{\purple{Area_{(Pizza)} = 50.24 \: {ft}^{2}}}}}}\)

Answers
If the archaeologist found a fossil whose length is 489.44 inches, using the conversion table, the length in feet, to the nearest tenth, is 40.8 feet.
What is the conversion table?The conversion table refers to the tabulated standard units of measurement, showing temperature, length, area, volume, weight, and metric conversions
For instance, the conversion table shows that 12 inches equal 1 foot.
The length of the fossil = 489.44 inches
12 inches = 1 foot
489.44 inches = 40.8 feet (489.44 ÷ 12)

naina made a 10 layer multi strand ornament for her friend Diana. She used 45 beads for the first layer, 42 beads in the 2nd layer and 39 beads in the third layer. how many total beads did naina use to complete the ornament
Answers
Answer:
To find the total number of beads Naina used to complete the ornament, we need to sum the number of beads in each layer.
Total number of beads = 45 + 42 + 39 + ... (continue the pattern until the 10th layer)
Notice that the number of beads in each layer decreases by 3. We can use arithmetic series formula to find the sum of the beads in all 10 layers:
S = (n/2) x (a + l)
where S is the sum, n is the number of terms, a is the first term, and l is the last term.
Here, a = 45, l = 18 (since the 10th layer will have 18 beads), and n = 10 (since there are 10 layers). Thus, we have:
S = (10/2) x (45 + 18) = 5 x 63 = 315
Therefore, Naina used a total of 315 beads to complete the ornament.
Answer:
The answer to your problem is, 1260
Step-by-step explanation:
Well we know she made 10 “ strand ornaments “ for each layers we would need to add;
45 + 42 + 39
= 126
We would actually then need to multiply it by 10. Shown:
126 × 10
= 1260
Thus the answer to your problem is, 1260

What is the intersection of two graphs?Since the point of intersection is the sole location where the two graphs come together, the coordinates of that location provide the answer to the equations involving the two variables. There are no solutions when the graphs are in parallel.
Given, the parabola Y = X² -2 and a line Y = -X. To find the intersection points of this graph we need to compare these equations.
Let's put the value of y in equation 1
- X = X² - 2
X² + X - 2 = 0
