1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
2. Wait patiently for a helper to come along.
3. Once someone helps you, say thank you and close the thread with:

   +close
   

4. Feel free to nominate the person for helper of the week in #helper-nominations
5. Do not ping the mods, unless someone is breaking the rules.
6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

so this wording is a tad bit confusing but

the length of your arc

is 17 inches

with that in mind

can you make progress on the question?

[summer citrus]

What does it mean when it’s asking for the measure of the central angle? The radians? Would I use the formula theta=subtended arc/radius?

[tawdry crown]

you can do it in either degrees or radians, you just need to include the units

[summer citrus]

Could you just please solve it so I can see the work process? It would be a huge help.

[tawdry crown]

we dont give the answers out here, but heres like a huge hint

[summer citrus]

Okay but you didn’t answer my question. Can I use the formula I mentioned above?

[tawdry crown]

^

[summer citrus]

Can I use that formula, yes or no?

[tawdry crown]

yea

you can use either of the formuals

[summer citrus]

Theta=17/13 which is equal to 1.307. Now what? @tawdry crown

@tawdry crown That’s what I did before but multiplied is by 360 and it was wrong.

[tawdry crown]

well, what unit is theta in for this case

is it degrees, or radians

[summer citrus]

Radians

[tawdry crown]

so, you can leave your answer in radians btw

if you just specify like that

unless theres more context above or smthn

[summer citrus]

So the answer is 1.307 radians?

[tawdry crown]

well preferably dont decimal and round it

just leave it in fraction form

unless, again, youre told otherwise

[summer citrus]

17/13 radians?

[tawdry crown]

17/13 rad for me would be an acceptable answer yea

[summer citrus]

Nothing else is told otherwise.

[tawdry crown]

then it should be fine

[summer citrus]

So what’s an explanation for what I did wrong? I shouldn’t have multiplied it by 360?

[tawdry crown]

to go from radians to degrees, what do you have to do?

its not multiply by 360

[summer citrus]

Can you help with b? @tawdry crown

@tawdry crown

[mild pecan]

Please don't spam ping him

[summer citrus]

My bad, can you help?

[tawdry crown]

sorry i had some stuff to do

[summer citrus]

No problem

[tawdry crown]

hmm this is pretty close i guess

but, when the angle is pi/2, where is he on the wheel? just draw it out

[summer citrus]

I corrected it. Is this better?

[tawdry crown]

do you know what the angle in radians is lol

like which angle

from the top, or

from his position

like i think it might be reference angle but

[summer citrus]

He starts from the 3’oclock position

It going from where he starts (3 o’clock) and is going in the counter clockwise direction.

[tawdry crown]

reference angle yippee

well, when it has spun pi degrees, how far from the right of the vertical diametre is it

[summer citrus]

Could you just tell me if it’s correct or not? I already did the work.

[tawdry crown]

that basically tells you the answer

once you think about it

[summer citrus]

Is it correct? Yes or no.

[agile blade]

Theta/360 (pi* 13^2) = 17

[flat hollow]

Isnt it Theta/360 (pi* 13*2) = 17?

[agile blade]

oh yeah
