\(\Huge\color{blue}{ \bf C=2rπ }\)

\(\Huge\color{blue}{ \bf 12.4=2r(3.14) }\)


\(\Large \color{blue}{ \bf Can ~~~you~~~solve~~~for~~~r? }\)

Answer 2

6.2 is answer

Answer 3

I would round the answer to the nearest hundredth, because that's relevantly exact, yet short.

Answer 4

well yea i guess six

Answer 5

Also, that's certainly not the answer. Not even close!

Answer 6

oh how

Answer 7

How? you have to solve for r, and I have no clue how in the world have you got 6 .

Answer 8

well r is radius right

Answer 9

Yes, r is radius.

Answer 10

duh !

Answer 11

well ok so 12.4 is the diameter right

u got it

Answer 17

r=4.63 ? @SolomonZelman

Answer 18

yea but did ya c the vedio

Answer 19

\[\large \frac{12.4}{2\pi} = r\]
r = 4.63 is Not quite what I get

Answer 20

oh well than did ya c the vedio

Answer 21

so what is the radius? @johnweldon1993
