Question

will fan & medal :) (dont get what they are asking)

Which of the following is not equivalent to the formula for the circumference of a circle, C = 2pir ?

C over pi equals 2 times r
C over the quantity of r times pi equals 2
Cr = 2pi

Answer 1

Answer 2

A)C over r equals 2 times pi
C/r = 2*pi because we divided both sides by r

B)C over pi equals 2 times r
C/pi = 2* r because we divided both sides by pi

C)C over the quantity of r times pi equals 2
C/(pi*r) = 2 because we divded both sides by pi * r

D)Cr = 2pi this is WRONG BECAUSE

C = 2*pi * r
you cant do any math to get C*r without an r on the other side too

Answer 3

OHHHHHHH that was easy ... ughh idk why i didnt try harder ... thank you so much
