Hint: the points in the circumference can be obtained using:

x = xCenter + r * cos angle

y = yCenter + r * sin angle

"sin" and "cos" expect the angle to be measured in radians, instead of degrees. To convert from one unit to the other, you must remember that 360 degrees = 2 PI radians (or 180 degrees = PI radians): float radians = (angle * Math.PI / 180.0);

You might draw 72 points (as there are 360 degrees in a circumference, they would be spaced 5 degreees from each other)

Hint: in Visual Basic (VB.net), cosine is Math.Cos, sine is Math.Sin and PI is Math.PI
