@carlyleukhardt can you help me with this equation? i got the answer D. then o got the answer C. please help me

- carlyleukhardt

The answer is C

- anonymous

Yes the answer is C

- anonymous

I was trying to give you the reason why its c

- jakyfraze

please do @Jazzy17999

- anonymous

okay

- anonymous

C=2PI*r
r=C/2PI=27/6.28 inches
2pi = 6.28
so, you have
2pi r = C
6.28r = 27
now just divide by the 6.28 to get r.
When you divide 27 by 6.28 you get 4.29936305732
rounded is 4.30
As I said before R is C (4.30)

Hope this helps u understand

@jakyfraze

- jakyfraze

@Jazzy17999 im not sure. can you sure me please? 30 x 3.14?

- anonymous

Yes that is how @jakyfraze you multiply 30 by 3.14 in this case to find the radius.

- jakyfraze

@Jazzy17999 but some questions you have to use pi2= 6.28 or pi= 3.14

- anonymous

yup

- jakyfraze

@Jazzy17999 why is that? please tell me. I'm really confuse

- anonymous

pi2 is 2x 3.14=6.28

- anonymous

What grade r u in?

- anonymous

7th or 8th?

- anonymous

btw if u want to learn more about circumference http://www.mathgoodies.com/lessons/vol2/circumference.html
here's a good website. @jakyfraze

- jakyfraze

yeah i know that but some questions i did i didn't have to you pi2= 6.28, i had to use 3.14

- anonymous

That was for a specific problem that u did it's not for every problem.

- anonymous

i have to go but, i hope all that helped.

- jakyfraze
