The volume of this right circular cylinder is 64π cubic yards. If h, the height of the cylinder, is 4 yards, what is r, the radius of the base?

Answers

Answer 1

Answer:

h = 4 cm

Step-by-step explanation:

The formula for volume of a cylinder is

V = πr²h      where V is the volume, r is the radius, and h is the height.

We are given V = 64π, and r = 4, plug those in and solve for h

64π = π(4²)h

64π = 16πh

(64π)/(16π) = (16πh)/(16π)      (divide both sides by 16π)

4 = (16π)/(16π)h

 4 = h

Answer 2
Answer:

Radius = 4 yards

Solution:

Here, we are provided a right circular cylinder with :

Volume = 64 π cubic yards Height = 4 yards Radius = ?

We know that :

[tex] \quad\hookrightarrow\quad{\pmb{ \mathfrak { Volume = \pi r^2 h }}}[/tex]

Therefore,

[tex] \implies\quad \sf{V = \pi r^2 h }[/tex]

[tex] \implies\quad \sf{64\pi = \pi r^2 \times 4 }[/tex]

[tex] \implies\quad \sf{ \pi r^2 \times 4 = 64\pi}[/tex]

[tex] \implies\quad \sf{r^2 =\dfrac{64\pi}{\pi \times 4} }[/tex]

[tex] \implies\quad \sf{ r^2 =\dfrac{\cancel{64}}{\cancel{4}}\times \cancel{\dfrac{\pi}{\pi}}}[/tex]

[tex] \implies\quad \sf{ r^2 = 16}[/tex]

[tex] \implies\quad \sf{r=\sqrt{16} }[/tex]

[tex] \implies\quad \underline{\underline{\pmb{\sf{r= 4}}} }[/tex]

Solve the system of linear equations.

Do I put into point slope form??

Answers

Answer:

The simple answer, "Yes"

Answer:

Point slope form of the equations:

y = -3x + 8

y = 2x - 2

Solution to the system of equations:

(x, y) ==> (2, 4)

Step-by-step explanation:

6x + 2y = 16

2x - y = 2

6x + 2y = 16

2(2x - y = 2)  ==> 4x - 2y = 4

6x + 2y = 16

4x - 2y = 4

10x = 20

/10     /10

x = 2

Now, we solve for y:

6x + 2y = 16

6(2) + 2y = 16

12 + 2y = 16

-12         -12

2y = 4

/2   /2

y = 2

(x, y) ==> (2, 2)

Point-slope forms:

6x + 2y = 16

-6x          -6x

2y = -6x + 16

/2        /2

y = -3x + 8

2x - y = 2

-2x      -2x

-1y = -2x + 2

/-1       -1

y = 2x - 2

Answer:

$33.91

Step-by-step explanation: Take 35% and change it to .35 now multiply 96.88 by .35 and you will get 33.908 round up to 33.91

Answer:

33.908

Step-by-step explanation:

To find the percentage of a certain number, you need to convert the percentage into its decimal form (0.35) and multiply it by the certain number. Then you'll have your answer!

0.35*96.88=33.908

33.908 is 35% of 96.88

Here's another example! Let's say you want to find 45% of.... 78!

45% is 45/100. The first step is to convert 45% into its decimal form. (45/100=0.45)

Then you multiply the decimal by the number you want to find the percentage of!

0.45*78=35.1

35.1 is 45% of 78!

Using known formulas for cylinders, we will get:

i) 4,000.36 cm^3ii) 4,000.36 cm^3iii) 1,142.96 cm^2.

Working with cylinders:

We know that the pot has a diameter of 10cm and a height of 21 cm, and the hole must be 4 cm wider (so the diameter is 14cm) and 5 cm deeper (so the height is 26cm).

i) The volume of a cylinder of radius r and height H is given by:

V = pi*r^2*H

Where pi = 3.14, and the radius is half the diameter, so we have:

r = 14cm/2 = 7cm.

Then the volume is:

V = 3.14*(7cm)^2*26cm = 4,000.36 cm^3

ii) To fill a volume of 4,000.36 cm^3, you need 4,000.36 cm^3 of water.

iii) The curve surface of a cylinder is given by:

S = 2*pi*r*H

Remember that:

r = 7cm

H = 26cm.

Replacing that we get:

S = 2*3.14*7cm*26cm = 1,142.96 cm^2

So se must paint an area of 1,142.96 cm^2.

The county health inspector will select a random sample of 4 community swimming pools in the county to investigate the pH levels. (b) Describe the sampling distribution of the sample mean for samples of size 4.

Answers

Using the Central Limit Theorem, considering a normally distributed population with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution is normal, with mean [tex]\mu[/tex] and standard deviation [tex]0.5\sigma[/tex].

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

Hence, considering a normally distributed population with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], and with the sample size of n = 4, the mean remains the same while the standard deviation is given by:

[tex]s = \frac{\sigma}{\sqrt{4}} = 0.5\sigma[/tex]
