OpenStudy (anonymous):

what do you need

OpenStudy (anonymous):

Areas of Circles

OpenStudy (anonymous):

yup! whats your quesetion

OpenStudy (anonymous):

Which circles have an area of 9pi m2? Choose all answers that are correct. A. a circle with a radius of 3 m B. a circle with a diameter of 6 m C. a circle with a radius of 9 m D. a circle with a diameter of 9 m

OpenStudy (anonymous):

one sec. another kid just asked me a question. be right back

OpenStudy (anonymous):

Ok

OpenStudy (anonymous):

okay is it 2m or m2

OpenStudy (anonymous):

m2

OpenStudy (anonymous):

@abbychandler

OpenStudy (anonymous):

sorry. yea im not so sure about this... what math are you in?

OpenStudy (anonymous):

7th grade

OpenStudy (anonymous):

okay i think you worded the question wrong then because im in calculus and if i cant figure this out then thats bad hahaha

OpenStudy (anonymous):

@dtan5457

OpenStudy (wolf1728):

Area = PI*r^2

OpenStudy (anonymous):

yes. but is 9 the radius? diameter? what is it. and then idk what the m2 is either

OpenStudy (wolf1728):

What does 9pi m2 mean? You typed it.

OpenStudy (anonymous):

me? or pie lover?

OpenStudy (wolf1728):

I was talking to pielover

OpenStudy (anonymous):

oh okay.

OpenStudy (wolf1728):

that's okay :-)

OpenStudy (wolf1728):

pielover, did you type that problem from a book?

OpenStudy (anonymous):

i dont think she/he's with us anymore lol

OpenStudy (anonymous):

no its a partice quiz

OpenStudy (wolf1728):

Can you type what you are reading from EXACTLY what it says?

OpenStudy (anonymous):

ok Which circles have an area of 9Pi m^2? Choose all answers that are correct. A. a circle with a radius of 3 m B. a circle with a diameter of 6 m C. a circle with a radius of 9 m D. a circle with a diameter of 9 m

OpenStudy (anonymous):

ohhhhhhh m^2 that makes a lot more sense

OpenStudy (wolf1728):

Is that exactly what the question says or is it more like 9*PI*m²

OpenStudy (anonymous):

Yes

OpenStudy (wolf1728):

Darned open study doesn't permit specail characters like "squared"

OpenStudy (anonymous):

lol

OpenStudy (wolf1728):

Is there any number between the word PI and the "m"?

OpenStudy (anonymous):

no

OpenStudy (wolf1728):

I'd say the answer is A

OpenStudy (anonymous):

Thanks!

OpenStudy (anonymous):

yeah. i agree

OpenStudy (wolf1728):

Okay we agree !!!

OpenStudy (anonymous):

hahaha

OpenStudy (anonymous):

Thanks so much to the both of you Bai!
