Hello,

I need to create a function which takes parameters for a circle and checks if a given point(x,y) lies within the circle (or on the edge).

Like this:

```
public static bool PointExistsInCircle(Double CircleX,Double CircleY,Double CircleRadius,Double PointX,Double PointY)
{
needs to return 'true' if the point is in the circle, if not return 'false'.
}
```

Could someone help me with this?, unfortunately i'm not good at math..

Mervin.
