I know that C=3.14 * radius squared, but can someone help me with a formula to plot points on a circle?

Thanks!!!

Are you saying that C is area? Area=pi*r^2 but cirumference=2*pi*r. There are a couple of ways. Firstly, as the graph of a circle is y^2+x^2=r^2 you can use if statements to check points are on the circle. The alternative is to use sin/cos.
Using 1st idea:

Using 2nd idea:

Hope that helps.
