Hi,

I'm stuck up with this problem that I have.

What I have is the center of the circle (x,y) and the radius.

With these values is there any formula to find out the five co-ordinates which would form a regular pentagon.

I need this to be implemented in a programming language so the formula needs to be something like

x1=so and so

y1= so and so

x2 = soand so

..

..

..

Can anyone please help me with this.

I'm really stuck up and need a help.

Thanks in advance.
