How many pieces of circular track, (Nickel gray E-Z track), Do I need to make a full circle with:
12.50" radius ?
or
11.25" Radius ?
Here's a simple trick most track will also have the degree on it, like 15 or 30 degree
just divide 360 by the degree 360 / 30 = 12
regardless of the radius 30 degree track will take 12 pieces to make a 360 degree circle.
