Can some one point me in the right direction on how I can divide a circle to get different regions for a dart board?

Can some one point me in the right direction on how I can divide a circle to get different regions for a dart board?
You’re using a cylindrical coordinate system: it’s best to express everything in terms of (r, theta) instead of (x, y).
Here’s how the two are related:
If you do that it’s easy.
I see seven different radii and twenty angular sections, so each angular section has to be 18 degrees each.
The angular section around the 20 is centered about the vertical. Pick a line for
theta = 0and start from there. (Two good choices might be horizontal to the right or the center of the 20.)Just one caveat: Remember that computers usually implement trig functions to take radians, not degrees. 360 degrees in a circle is intuitive for most people, but computers will prefer 2π radians.
