the volume of two similar solids are 1080cm and 1715cm .if the curved surface area of the smaller cone is 840cm .fond the curved surface area of the larger cone
Answer:
[tex]A_{big} = 1143.33cm^2[/tex]
Explanation:
The given parameters are:
[tex]V_{small} = 1080[/tex]
[tex]V_{big} = 1715[/tex]
[tex]C_{small} = 840[/tex]
Required
Determine the curved surface area of the big cone
The volume of a cone is:
[tex]V = \frac{1}{3}\pi r^2h[/tex]
For the big cone:
[tex]V_{big} = \frac{1}{3}\pi R^2H[/tex]
Where
R = radius of the big cone and H = height of the big cone
For the small cone:
[tex]V_{small} = \frac{1}{3}\pi r^2h[/tex]
Where
r = radius of the small cone and H = height of the small cone
Because both cones are similar, then:
[tex]\frac{H}{h} = \frac{R}{r}[/tex]
and
[tex]\frac{V_{big}}{V_{small}} = \frac{\frac{1}{3}\pi R^2H}{\frac{1}{3}\pi r^2h}[/tex]
[tex]\frac{V_{big}}{V_{small}} = \frac{R^2H}{r^2h}[/tex]
Substitute values for Vbig and Vsmall
[tex]\frac{1715}{1080} = \frac{R^2H}{r^2h}[/tex]
Recall that:[tex]\frac{H}{h} = \frac{R}{r}[/tex]
So, we have:
[tex]\frac{1715}{1080} = \frac{R^2*R}{r^2*r}[/tex]
[tex]\frac{1715}{1080} = \frac{R^3}{r^3}[/tex]
Take cube roots of both sides
[tex]\sqrt[3]{\frac{1715}{1080}} = \frac{R}{r}[/tex]
Factorize
[tex]\sqrt[3]{\frac{343*5}{216*5}} = \frac{R}{r}[/tex]
[tex]\sqrt[3]{\frac{343}{216}} = \frac{R}{r}[/tex]
[tex]\frac{7}{6} = \frac{R}{r}[/tex]
The curved surface area is calculated as:
[tex]Area = \pi rl[/tex]
Where
[tex]l = slant\ height[/tex]
For the big cone:
[tex]A_{big} = \pi RL[/tex]
For the small cone
[tex]A_{small} = \pi rl[/tex]
Because both cones are similar, then:
[tex]\frac{L}{l} = \frac{R}{r}[/tex]
and
[tex]\frac{A_{big}}{A_{small}} = \frac{\pi RL}{\pi rl}[/tex]
[tex]\frac{A_{big}}{A_{small}} = \frac{RL}{rl}[/tex]
This gives:
[tex]\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{L}{l}[/tex]
Recall that:
[tex]\frac{L}{l} = \frac{R}{r}[/tex]
So, we have:
[tex]\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{R}{r}[/tex]
[tex]\frac{A_{big}}{A_{small}} = (\frac{R}{r})^2[/tex]
Make [tex]A_{big}[/tex] the subject
[tex]A_{big} = (\frac{R}{r})^2 * A_{small}[/tex]
Substitute values for [tex]\frac{R}{r}[/tex] and [tex]A_{small}[/tex]
[tex]A_{big} = (\frac{7}{6})^2 * 840[/tex]
[tex]A_{big} = \frac{49}{36} * 840[/tex]
[tex]A_{big} = \frac{49* 840}{36}[/tex]
[tex]A_{big} = 1143.33cm^2[/tex]
Hence, the curved surface area of the big cone is 1143.33cm^2

what is the difference between cd-r, cd-rw and cd-rom
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"difference between cd-r, cd-rw and cd-rom"
CDs are also known as WORM discs,for "write once Read many".A re writable version based on excitable crystals and known as CD-RW was introduced in the mid 1990s because both CD-R and CD-RW recorders originally required a computer to operate they had limited acceptance of use as computer software.
A compact Disc Read only memory (CD-ROM) is a read only disc.A compact disc Re-writable (CD-RW) is an erasable disc that can be reused.The data on a CD-RW disc can be erased and recorded over numerous times.CD-RW may not be readable outside of the drive it was created in.
cd-r :
CD-R is a digital optical disc storage format.A CD-R disc is compact disc that can be written once and read arbitrarily many times.
CD-R stand for" compact disc" Record-able .CD-R disc are blank CDs that can record data written by a CD burner.The word "record-able" is used because CD-R are often used to record audio,Which can be play back by most CD players.
cd-rw:
CD-RW compact disc re-writable is a digital optical disc,storage format introduced in 1997.A CD-RW compact disc can be written read erased and re-written.
in this case of CD-RW the writing laser makes permanent marks in a layers of dye polymer in the disc.CD rewrite-able discs in a similar fashion,except that the change to the recording surface is revers able.
cd-rom:
CD-Rom observation of compact disc read only memory type of computer memory in the form of compact disc that is read by optical means.A CD-ROM drive uses a low power laser been encoded in the form of tiny pits on a optical disk.The "ROM" part of the term means the data on the disc "read only memory" or cannot be altered or erased.
To transfer files to your company's internal network from home, you use FTP. The administrator has recently implemented a firewall at the network perimeter and disabled as many ports as possible. Now you can no longer make the FTP connection. You suspect the firewall is causing the issue. Which ports need to remain open so you can still transfer the files? (Select TWO
Answer:
Ports 20 and 21
Explanation:
For the FTP to work, there are two parts that are required; the command and the data. These two parts are sent on the two ports 21 and 20 respectively. If the firewall is indeed blocking connections on ports 21 and 20, then your FTP will not work.
Hence, you need to open ports 20 and 21 to allow FTP to remain functional.
Cheers.

Explore the program below, referring to the task description to know what task the chunk of code is supposed to execute. Explain why the program is not working as intended, then rewrite/rework the program so that it performs the intended task as stated in the description.
The following situation uses a robot in a grid of squares. The robot is represented by a triangle which is initially in the top left square and facing right. The robot may not travel through the black squares. The program below is intended to move the robot from its starting position to the gray square, but it is not currently working. The program segment uses the procedure called GoalReached , which evaluates to true if the robot is in the gray square and evaluates to false otherwise.
In complete sentences, explain why the program is not working as intended, and also provide a solution that allows the program to perform its intended task.
Answer: It is not working because it is missing the code needed to turn right.
Sentence :The robot would move forward two squares and would stay stuck there because it can not move forward nor turn left. You would need to add code for the robot to be able to turn right so that the robot can reach the goal
There are several reasons that could make a code segment not to work.
The attached code is not working because, the method ROTATE_RIGHT() is missing
From the given code segment, we have the following observations
The robot can turn left using ROTATE_LEFT()The robot can move forward using MOVE_FORWARD()However, when there is a need for the robot to turn right, the code segment does not have a provision for that.
Hence, the reason the code is not working is because:
The method ROTATE_RIGHT() is missing
The solution to this is to provide a ROTATE_RIGHT() method in the code segment
