Density and distribution of stars are directly affected when the change occur in the size of the circle.
<h3>Effect on density </h3>
The density and distribution of "stars" changed as the circle gets larger because when the circle gets larger, its volume increase which results in the decrease in the density. The distribution of stars also changed due to more space or volume present in the medium.
<h3>Distribution</h3>
If the universe is more condensed, then the stars are more closer together but when the universe is more expand then the stars are present farther away from each other so we can conclude that density and distribution of stars are directly affected when the change occur in the size of the circle.
