[25 POINTS] A cylinder has a volume of 400π cm3. Find the dimensions that minimize its surface area.

Answers

Answer:

r = 5.848cm, h = 11.696cm

Step-by-step explanation:

Surface area: [tex]SA=2\pi rh+2\pi r^2[/tex]

Volume: [tex]V=\pi r^2h[/tex]

Therefore, the height of a cylinder given its volume would be [tex]h=\frac{V}{\pi r^2}[/tex], thus:

[tex]SA=2\pi r(\frac{V}{\pi r^2})+2\pi r^2\\\\SA=\frac{2V}{r}+2\pi r^2\\\\SA=\frac{2(400\pi)}{r}+2\pi r^2\\\\SA=\frac{800\pi}{r}+2\pi r^2[/tex]

We now find the derivative of the surface area of the cylinder with respect to its radius and set it equal to 0, solving for the radius:

[tex]\frac{d(SA)}{dr}=-\frac{800\pi}{r^2}+4\pi r[/tex]

[tex]0=-\frac{800}{r^2}+4\pi r[/tex]

[tex]0=800\pi+4\pi r^3[/tex]

[tex]-800\pi=4\pi r^3[/tex]

[tex]-200=r^3[/tex]

[tex]r\approx5.848[/tex]

If [tex]0If [tex]r>5.848[/tex], then the surface area of the cylinder increases

Therefore, the surface area is minimized when the radius is [tex]r=5.848cm[/tex], making the minimum height [tex]h=\frac{V}{\pi r^2}=\frac{400\pi}{\pi(5.848)^2}\approx11.696cm[/tex].

In conclusion, the 2nd option is correct.

The women of latvia are the tallest in the world with an average height of 170 cm, which is what in feet and inches?.

Answers

Step-by-step explanation:

Convert the given value in cm into feet and inches.

Use the unit rates:

1 foot = 30.48 cm1 inch = 2.54 cm

Convert:

170 cm = 170/30.48 feet = 5.58 feet (rounded)170 cm = 170/2.54 inches = 66.93 inches

or

170 cm = 5 feet and 17.6 cm = 5 feet and 7 inches (rounded)

a certain pet store sells only dogs and birds. They have a total of 71 animals in the store currently
A story employee walked around and counted a total of 246 legs. How many of the animals are
dogs?

Answers

Answer: 52 Dogs

Hi, I hope this helps you :D Good Luck !

Step By Step:

Let d = number of dogs

b = number of birds

d+b = 71

Birds have 2 legs and dogs have 4 legs

4d+2b = 246



Multiply the first equation by -2

-2d-2b = -142

Add this to the second equation



-2d-2b = -142

4d+2b = 246

--------------------------

2d  + 0b = 104

Divide each side by 2



2d/2 = 104/2

d = 52



There are 52 dogs

You can use the fact that the corresponding values from both the columns are taken into ordered pair (x,y) form to plot them on the 2d graphs (for 2 data values' set)

The scatter plot best representing the data in the table is given by

Option D:   Plots ordered pairs 0, 23. 5 and 500, 12 and 1000, 6 and 1500, 4. 2 and 2000, 4 and 2500, 3. 8 and 3000, 3 and 3500, 2. 8 and 4000, 2.

How are ordered pairs formed for plotting 2d data?

There are two axis in the graph. Horizontal axis and vertical axis. The independent variable is plotted on horizontal axis and dependent variable's values are plotted on vertical axis.

Since the temperature is measured on each value of depth, thus, depth is independent and temperature is depending on the depth.

The data points are ordered as

(independent variables' value, dependent variables' value at that value of independent variable)

Thus, for the given table, we will have:

(0, 23.5), (500, 12), ... points.(it is denoting like what was the value of second variable when first variable was this. Like when depth was 0, temperature was 23.5 degrees Celsius, and so on).

Thus,

The scatter plot best representing the data in the table is given by

Option D:   Plots ordered pairs 0, 23. 5 and 500, 12 and 1000, 6 and 1500, 4. 2 and 2000, 4 and 2500, 3. 8 and 3000, 3 and 3500, 2. 8 and 4000, 2.

Answers

Answer:

Mean: 11.6

Median: 14

Mode: 18

Range: 17

Step-by-step explanation:

Mean: add all of the numbers and divide by how many numbers there are

Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

Mode: the number that occurs the most

Range: Subtract the minimum data value from the maximum data value to find the data range. In this case, the datarange is 18−1=17

What is a clapperboard and why was it important? Read the passage.Saving the Apollo 13 MissionOn April 11, 1970, Apollo 13 was launched for a planned moon landing. Two days into the mission, however, one of the oxygen tanks in the spacecraft exploded, causing a loss of air, electricity, and water. The moon landing had to be canceled, and the astronauts had to figure out how to get home. Their solution was to move into the lunar module, the small craft that was supposed to land on the moon, for much of the remaining trip. The lunar module contained fewer supplies, however. Therefore, the astronauts had to conserve as much food and water as possible. By firing the lunar module's engine, the men were able to get the spacecraft on the correct course to return to Earth.
