Aparticular spiral galaxy can be approximated by a thin disk-like volume 62 thousand light years in radius and 7 hundred light years thick. if this galaxy contains 1,078 billion stars, estimate the average distance between the stars in this galaxy. hint: calculate the average volume per star in cubic light years, and then estimate the approximate linear dimension across such a volume. (indicate your answer to one decimal place.)
