Derive Circumference of a Circle

by the definition of pi (π) is the circumference c of any circle divided by its diameter d

Put as an equation, pi is defined as π=c/d
Rearranging this to solve for c we get c=π*d

The diameter of a circle is twice its radius, so substituting 2r for d
c=2π*r

Is that all it takes to derive the circumference of a circle?
