What is the circumference of a circle? I means the formula.
Is it C=2(pie)r
Yes, C = 2(pi)r
2(pi)r is the length around the entire circle, all 360 degrees of it. Here you only want the length along 60 degrees of it.
Would i make be 60 ?
The sector length, s = (n/360)2(pi)r
s = 60/360 (2)pi(r)
s = 0.17 2(pi)30 ?
Am i doing it right so far
s = 0.17 + 188.4
s = 188.57
Wait, how do you get a + signe in there? Everything is multiplied together.
I thought you had to add them -__ -
s = (60/360)*2*pi*30 = (1/6)*2*3.14*30
s = 32.03 ?
I have to round
What did you use for pi?
Use 0.1666666 for 60/360
31.399987 since i have to round to the nearest hundredth it would be 31.40 ?
What a neat little problem!!! That formula was enough to make 10 pis!!! :-)
Do you have a scientific calculator?
I have a texas instruments calculator is that one ? ahaha
Does is have a key for pi?
Yes but whenever i do a problem with pie it's just do this 6pie3 = 18pie
it* does *
Enough to make 10 pies, does that mean i divide 360 by 10 ?
No, I was referring to the final answer you'll eventually get. It surprised me. :-)
I haven't got the answer yet ?! FML -__ -
31.4 is probably close enough for your schoolwork, but the answer when you use pi taken out to more places is interesting. I may as well stop kibitzing from the sidelines here...I used 3.14159 as pi for my calculations and got 31.4159 as a solution. IOW, 10 pi :-)
I was way off lucky me
Wait so you did 10(pi) and that was it ?
Not really. 31.39999... is 31.4 which is the same answer as I got, but accurate to 1 place, is all. And I hope that mathstudent55 doesn't take offense at my "kibitzing from the sidelines" here. I only jumped in after you had already pretty much gotten the answer with his help.
It's fine mathstudent55 isn't online (:
No. I didn't "do" 10(pi), the answer just happened to be 31.4159 which just happens to also be 10*pi.
And I thought that was humorously interesting. :-) Or interestingly humorous... :-)
I see, how did you get 10 though ?
Ummmm....by dividing 31.4159 by 3.14159 ???
Oh ahaha oblivious me sorry for exuding slowness. (:
Heheh...I see you've had an epiphany!! :-) All is good now!! :-)
Hopefully it is, i'm getting way too frustrated with this and it's not even afternoon yet.
No problem. Sometimes ya have to just walk away for awhile. Grab some munchies and sit outside smelling the air. It'll come to you, just don't let it atke you over. :-)
Insightful, thanks. I'll do that and thank you for making it less stressful
No problem! Don't think of them as "problems", think of them as "puzzles"! :-) Take care! :-)
