The first thing you should know in this case is that the circumference of a circle is given by:
 C = 2 * pi * r
 Where,
 r: radius of the circle.
 We have then that the following equation is not equivalent to the circumference of the circle:
 Cr = 2
 Answer:
 The following is not equivalent to the formula for the circumference of a circle:
 Cr = 2
