The diameter of a circle is twice its radius.
since the equation to get circumference is diamiter X pi, and the diamiter is 2x the radius, yes it would double the C of the circle ie before radius is 2, so diamiter is 4 4 X Pi 12.57... radius is 4 so the diamiter is 8 8 X pi = 25.13... that would double it.
circumference = diamiter times pie 3.14 times 10 move the decimal over once its 31.4
the ratio of the diamiter of the axel to the diamiter of the weel have a smaller ratio to improve acceleration a larger ratio to improve distance or top speed
