OpenStudy (anonymous):

OpenStudy (bohotness):

are you sure its d i am doing study island 7 grade

OpenStudy (anonymous):

do u know the circumfurence equation

OpenStudy (bohotness):

kind of

OpenStudy (anonymous):

3.14x r^2=circumference

OpenStudy (anonymous):

exactly

OpenStudy (girlover):

Ok first do you know how to find the circumference?

OpenStudy (bohotness):

i think 6 time 6 times 3.14??

OpenStudy (bohotness):

6 b :D

OpenStudy (girlover):

3×3=9 but thats not all you have to multiply by pi=3.14

OpenStudy (girlover):

C=2piR (2 times pi times 3= 6pi)

OpenStudy (girlover):

It would be 6pi as your answer. However does it say to keep pi as pi or 3.14

OpenStudy (girlover):

@bohotness

OpenStudy (bohotness):

oh

OpenStudy (girlover):

?

OpenStudy (bohotness):

k

OpenStudy (bohotness):
