2.) r = 2πC
3.) r = C − 2π
4.) r = 2 pi over C

Answer 1

wht do u think???

Answer 2

its same like
a = b/x
b = ax

Answer 3

I think 4.

Answer 4

why so??? o_O

Answer 5

if r = 2 pi C
then it means C = r/(2 pi)

Answer 6

r is on the right what do you have to do to leave r by itself?

Answer 7

this is an equation. whatever you do to one side also do to the other to maintain the balance

Answer 8

no

Answer 9
