The term 'arranged like spokes' can be described as 'RADIAL' in six letters. RADIAL means that something is arranged in a circular pattern, with each element radiating out from a central point like the spokes of a wheel. This arrangement is often seen in nature, such as the petals of a flower or the feathers of a bird. It is also used in many man-made designs, such as the layout of a city or the structure of a web page.
