The surface area of this cylinder is 1,582.56 square feet. What is the height?
There are five basic equations which completely describe the cylinder with given radius r and height h:
Volume of a cylinder: V = π * r² * h,Base surface area of a cylinder: A_b = 2 * π * r²,Lateral surface area of a cylinder: A_l = 2 * π * r * h,Total surface area of a cylinder: A = A_b + A_l,Longest diagonal of a cylinder: d² = 4 * r² + h².Sometimes, however, we have a different set of parameters. With this height of a cylinder calculator you can now quickly use ten various height of a cylinder formulas which can be derived directly from the above equations:
Given radius and volume: h = V / (π * r²),Given radius and lateral area: h = A_l / (2 * π * r),Given radius and total area: h = (A - 2 * π * r²) / (2 * π * r),Given radius and longest diagonal: h = √(d² - 4 * r²),Given volume and base area: h = 2 * V / A_b,Given volume and lateral area: h = A_l² / (4 * π * V),Given base area and lateral area: h = √(A_l² / (2 * π * A_b)),Given base area and total area: h = (A - A_b) / √(2 * A_b * π),Given base area and diagonal: h = √(d² - 2 * A_b / π),Given lateral area and total area: h = A_l / √(2 * π * (A - A_l)).help pls due in 5 minutes

a tuba creates a 4th harmonic of frequency 116.5 hz what is the length of the pipe in the tuba
Since the tuba creates a 4th harmonic of frequency 116.5 hz, the length of pipe in tuba is 6.57 m
Since the tuba is an closed-pipe instrument, we need to find the frequency of a closed pipe
What is the frequency of an closed pipe?The frequency of a closed pipe f = nV/4L where
n = harmonic V = speed of sound and L = length of pipe in tubaLength of pipe in tubaMaking L subject of the formula, we have
L = nV/4f
Since the tuba creates the 4th harmonic with frequency 116.5 Hz.
n = 9 and f = 116.5 HzSubstituting the values of the variables into the equation, we have
L = nV/4f
L = 9 × 340 m/s/4 × 116.5 Hz
L = 3060 m/s ÷ 466 Hz
L = 6.57 m
So, the length of pipe in tuba is 6.57 m

(HELP PLS) Monica is building her dream home. It will have a total floor area of 2.150 sq. ft.
a. If Monica wants the living room to be 30% of the total area, what would the living room's area be?
b. The house Monica currently lives in has only 65% of the floor area of her dream home. What is the floor area of her current home?
The living room area of Monica's home is 0.645 ft².
The floor area of her current home is 1.3975 ft²
How to find percentage of an area?
The total floor area of Monica's dream home should be 2.150 ft².
Monica wants the living room to be 30% of the total area. Therefore, the living room area will be as follows:
living room area = 30 / 100 × 2.150 = 64.5 / 100 = 0.645 ft²
Her current house has only 65% of the floor area of her dream house. Therefore, the floor area of her current home is as follows:
Floor area of her current home = 65 / 100 × 2.150
Floor area of her current home = 139.75 / 100
Floor area of her current home = 1.3975 ft²

x^2+11x+28/x^2+5x+4 simplify expression
Answer:
(x + 7)/(x + 1)
Step-by-step explanation:
Simplify the following:
(x^2 + 11 x + 28)/(x^2 + 5 x + 4)
The factors of 4 that sum to 5 are 4 and 1. So, x^2 + 5 x + 4 = (x + 4) (x + 1):
(x^2 + 11 x + 28)/((x + 1) (x + 4))
The factors of 28 that sum to 11 are 7 and 4. So, x^2 + 11 x + 28 = (x + 7) (x + 4):
((x + 4) (x + 7))/((x + 4) (x + 1))
((x + 7) (x + 4))/((x + 4) (x + 1)) = (x + 4)/(x + 4)×(x + 7)/(x + 1) = (x + 7)/(x + 1):
Answer: (x + 7)/(x + 1)
Next time write the expression how it needs to be, the way you wrote it woould have given a toally different result.

Answer:
solving this as you would in algebra 2:
x2+11x+28 / x2+5x+4 = x+7 / x+1
Step-by-step explanation:
solving this as you would in algebra 2:
x2+11x+28 / x2+5x+4
1. on both the top and the bottom you have to find a factor of the last number (in this case 28 and 4) that multiplys to be the number but adds to be the 2nd term (11x and 5x)
2. for the top the two terms would be (x+7) and (x+4). on thebottom half it would be (x+4) and (x+1)
** 7 times 4 equals 28, 7 plus 4 equals 11; 4 times 1 equals 4, 4 plus 1 equals
3. x+4 is common term on both the top side and the bottom half so you cross it out. this leaves us with our answer of: x+7 over x+1

Answers:
AC = 221.37 feet
BC = 181.34 feet
The values are approximate.
=========================================================
Explanation:
Focus on triangle ACD for now.
The 67 degree angle adjacent to angle D helps us find that angle D = 180-67 = 113 degrees.
Let's find the missing angle C.
A+C+D = 180
55+C+113 = 180
C+168 = 180
C = 180-168
C = 12
Now we can use the Law of Sines to find side d, which is opposite angle D. This is the segment AC.
[tex]\frac{\sin(C)}{c} = \frac{\sin(D)}{d}\\\\\frac{\sin(12)}{50} = \frac{\sin(113)}{d}\\\\d\sin(12) = 50\sin(113)\\\\d = \frac{50\sin(113)}{\sin(12)}\\\\d \approx 221.369 190\\\\d \approx 221.37\\\\[/tex]
Segment AC is roughly 221.37 feet long.
Keeping our attention on triangle ACD, let's find side 'a'. This is the segment CD.
[tex]\frac{\sin(C)}{c} = \frac{\sin(A)}{a}\\\\\frac{\sin(12)}{50} = \frac{\sin(55)}{d}\\\\a\sin(12) = 50\sin(55)\\\\a = \frac{50\sin(55)}{\sin(12)}\\\\a \approx 196.995 186\\\\[/tex]
Segment CD is roughly 196.995186 feet long.
----------------------------------------------
Now move onto triangle BCD.
Use the sine ratio to determine side BC.
[tex]\sin(\text{angle}) = \frac{\text{opposite}}{\text{hypotenuse}}\\\\\sin(\text{D}) = \frac{\text{BC}}{\text{CD}}\\\\\sin(67) \approx \frac{\text{BC}}{196.995186}\\\\\text{BC} \approx 196.995186*\sin(67)\\\\\text{BC} \approx 181.335025\\\\\text{BC} \approx 181.34\\\\[/tex]
Segment BC is roughly 181.34 feet long.

Then we have to solve the equation 3x + 11y = 100
Important: x and y are natural numbers
3x + 11y = 100 ⇔ 100 - 11y = 3x
If y=10 ⇒ 100 - 11×10 = −10 = 3x impossible because x ≥ 0
If y=9 ⇒ 100 - 11×9 = 1 = 3x impossible because x is a natural number
If y=8 ⇒ 100 - 11×8 = 12 = 3x ⇒ x = 12/3 = 4
Then (x,y) = (4,8) is a solution to the equation
If y=7 ⇒ 100 - 11×7 = 23 = 3x impossible because x is a natural number
If y=6 ⇒ 100 - 11×6 = 34 = 3x impossible because x is a natural number
If y=5 ⇒ 100 - 11×5 = 45 = 3x ⇒ x = 45/3 = 15
Then (x,y) = (15,5) is a solution to the equation
If y=4 ⇒ 100 - 11×4 = 56 = 3x impossible because x is a natural number
If y=3 ⇒ 100 - 11×3 = 67 = 3x impossible because x is a natural number
If y=2 ⇒ 100 - 11×2 = 78 = 3x ⇒ x = 78/3 = 26
Then (x,y) = (26,2) is a solution to the equation
If y=1 ⇒ 100 - 11×1 = 89 = 3x impossible because x is a natural number
If y=0 ⇒ 100 - 11×0 = 100 = 3x impossible because x is a natural number

What is the formula for finding the midpoint of a segment? Circle your choice.
Answer:
Choice D is the correct answer. (I assure you)
{Answer choice B is incorrect.}
The formula for finding the midpoint of a segment is :
( (x₁ + x₂)/2, (y₁ + y₂)/2). Hence, Option D is correct.
Use the concept of coordinates defined as:
A pair of numbers that describe the exact position of a point on a cartesian plane by using horizontal and vertical lines are called the coordinates.
Consider two opposite points of a segment (x₁, y₁) and (x₂, y₂).
Then x coordinate of the midpoint of the line joining this point is :
(x₁ + x₂)/2
And y coordinate of the midpoint of the line joining this point is :
(y₁ + y₂)/2
Therefore,
The coordinate of the midpoint of this segment is ( (x₁ + x₂)/2, (y₁ + y₂)/2)
Hence, Option D is the correct coordinate to find the midpoint.
