From that circle, you can determine both the circumference ... I can calculate the radius as the average distance from the center to all the points making up the circle. So I wrote this Python ...

Any point P with coordinates (\(x,~y\)) on the circumference ... the equation of a circle with radius \(r\) and centre (0, 0) is given by the formula \(x^2+ y^2= r^2\). Find the equation of ...

In particular, after a quick refresher of circle basics, we’re going to figure out why the equation for the circumference of ... of string to serve as the radius of the circle.
