I am trying to write a function that will randomly return an (x,y) co-ordinates around a given circumference so if I have a point that's at (0,0) (being the center of the div) how can I write a function that randomly places other entities that appear among the outer edge of a circle.
All I need is the equation i know it has something to do with getting the distance from the center to the circumference edge just no idea how to calculate it and randomize it so it looks good.

The simplest method would be to generate a random angle θ∈[0,2π]. Then convert from polar to Cartesian with (x,y)=(rcosθ,rsinθ). Note that if your random number generator returns a number k∈[0,1] then θ=2πk.
In python, there's an inbuilt method, “random. uniform()” which performs this task with ease and uses just one word. This method is defined in the “random” module. It Returns the generated floating-point random number between the lower limit and upper limit.
Just get a random angle:
var angle = Math.random()*Math.PI*2; Then
x = Math.cos(angle)*radius; y = Math.sin(angle)*radius; Done.
