Question

A cruise ship has circular windows in It's state rooms. What is the circumference of one of these windows If it's diameter is 15 inches ???

Answer 1

c = Pi * d

Answer 2

Or it could be written as \(c = \pi d\)

Answer 3

@gypsy1274

True. Did not want to go through the LaTex process.

Answer 4

@robtobey Your equation is perfectly clear - I'm just feeling silly.

Answer 5

@gypsy1274

Don't have any LaTex commands committed to memory.
Mathematica is able to copy LaTex and paste the result into a document.

Answer 6

That would be nice. It is a bit cumbersome to cut and paste equations here.

Answer 7

@xoxox123 c = circumference and d = diameter. Have you figured out the answer?

Answer 8

@robtobey Mathematica is expensive, do you use it at home or at work/school?

Answer 9

Here is an example.
Used the mouse to select the expression.
Right clicked the mouse and dragged to LaTex.
Clicked to place the LaTex code onto the openstudy insert page.
clicked the Insert button.
\[3 a^2 y \left(a^2 y^2-4 a y+2\right) \]

Answer 10

Nice. I'll have to stick with \(\LaTeX\) though. My budget doesn't allow for Mathematica.

Answer 11

On the price of Mathematica.
I bought Mathematica 8 Home Edition for $250 as I recall. The agreement is that I cannot use the program for pay.

Just upgraded to Mathematica 9 for $95.
Can't use it for openstudy because the LaTex feature does't work correctly.

Answer 12

Does that mean if I purchased the individual license that I could not use it to create worksheets for my students? Or that I can not use it to write books?

Answer 13

sorry i was eating dinner

Answer 14

c=3.14(15) ??

Answer 15

That's ok. Robtobey and I have been having an interesting conversation on your question thread.

Answer 16

Yes, that is correct.

Answer 17

i got 47.1

Answer 18

That is correct, unless your teacher wants the answer in terms of \(pi\). Be sure to check your instructions.

Answer 19

47.1 inches is wrong

Answer 20

@gypsy1274

Answer 21

Did you try \(15\pi\)? The calculation is correct and so is the formula.

Answer 22

Is the diameter 15 or the radius?

Answer 23

look in the problem it tells you

Answer 24

and how am i supposed to put that in the answer

Answer 25

Based on the question you wrote, the answer is 47.1 or \(15\pi\). As for how to input that answer, I have no idea what system or program you are using so I can't answer that. I was asking you to re-check to make sure you had provided accurate information.
Sorry, that is the best help I can give you.

Answer 26

how would i write the second answer

Answer 27

\(15\pi\)? I don't know how to enter it in your program. Look along the edges of the screen for options find a help screen. You could try the \(\LaTeX\) version, it looks like this: \pi

Answer 28

soo 15/pi

Answer 29

i think the website will mark it wrong like that

Answer 30

No. The slash is going the wrong way.

Answer 31

This is a question for someone familiar with your program or class. Maybe your teacher?

Answer 32

okay ..

Answer 33

could the answer be 15 inches

Answer 34

Only if your question is asking for the diameter. Based on your question above, 15 is the diameter and not the circumference.

Answer 35

so whats the circumference ? another way to write 47.1

Answer 36

Can you provide a screen capture? I might be able to make a better guess if I can see what you are looking at.

Answer 37

how do i do that ?

Answer 38

Depends on your computer. A windows computer may have a button labels "scr prt"

Answer 39

You may also have to use a drawing program like Paint to save the image in .jpg format to upload to this site.
