Interface And Graphics :: Draw A Circle On The Console?

I am trying to draw a circle on the visual basic console. I have been told that the console is not made for this but i have to use it.

What I want to do is a circle with:

Centre (40,20)
Radius = 10

I know from basic trig that the following will give me the points on the circle:

x= (10 x CosA)+40
y=(10 x SinA) +20
(A) being an angle in radians.

Then combine x & y that will give me a point on the circle.

I want to use the '' Sets the cursor position

Console.SetCursorPosition(x, y)
Console.Write(".") "

To print a point(.) on the given position from the formulas above.

Now heres my question how do I get Visual Basic too calculate:

x= (10 x CosA)+40
y=(10 x SinA) +20

360 times i.e 0rad-2Pirad and then pass the x & y [(x,y)] point to my cursor position code so that a '.' is printed at that position. I.e I will end up with a circle made out of 360 '.'

I would asume that a loop is used and also an array to store the 360 Pi values. I'm finding it extremely hard to even get Vb to calculate the Cos of an angle.
