the size of the cylinder is based on the size of the layer so a wider layer will have a larger radius.
i suppose if you had a specific radius value in pixels that you needed to create a cylinder with, you could actually calculate the width that you needed to create the layer to start with…
width = 2 * pi * radius
or if you needed to figure the radius of a cylinder that you already created…
radius = (2 * pi) / width
however, if the radius property was not 100%, you’d need to factor that into the equation too
radius = (2 * pi * percent) / (width * 100)
