OpenStudy (asnaseer):

You need to post your question

OpenStudy (saifoo.khan):

It's totally free. Dont worry.

OpenStudy (anonymous):

Yeah no CCs :)

OpenStudy (amistre64):

fan testimonials are not for "messaging" for the most part

OpenStudy (anonymous):

I wish there was a messaging feature on here.

OpenStudy (saifoo.khan):

Fan tests are used as messengers! :D

OpenStudy (amistre64):

i believe a messaging system would offer to much room for abuse of the system; not that creating your own group doesnt already :)

OpenStudy (anonymous):

I guess that's what forums are for :-/

OpenStudy (anonymous):

@Amistre:Good poitn lol. @Brine: People want shortcuts..so.. you get it xD

OpenStudy (anonymous):

the circumference of the circular pool is 56.5 what are the diameter and radius of the pool round to the nearest hundreth

OpenStudy (saifoo.khan):

Yes! Nice poitn.

OpenStudy (amistre64):

if we know the formula for circumference is: 2pi r the rest is in the details

OpenStudy (amistre64):

*cough cough*

OpenStudy (anonymous):

thanks guys

OpenStudy (anonymous):

Point* lol saif >_>

OpenStudy (amistre64):

circumference is a linear measure; so making it an area is a little much

OpenStudy (anonymous):

oh duh

OpenStudy (anonymous):

sorry

OpenStudy (anonymous):

what i dont get it

OpenStudy (anonymous):

circ = 2pi*r

OpenStudy (anonymous):

im only in the 9th grade

OpenStudy (anonymous):

56.6 = 2*pi*r

OpenStudy (amistre64):

9th graders can learn too

OpenStudy (anonymous):

r=(56.6)/(2*pi)

OpenStudy (anonymous):

im only in the 9th grade

OpenStudy (amistre64):

do 9th graders have a different way of finding the circumference of a circle?

OpenStudy (anonymous):

I mean there are people at my college who aren't able to do basic arithmetic. So you're way ahead of the game already.

OpenStudy (anonymous):

And it goes without saying that I applaud them for putting in the effort and taking the classes even if they're doing this stuff as an adult
