Equations of Circles

Drayton Valley Crop Circle
Originally uploaded by tkaminski.
On Thursday we studied how to determine the equation of a circle. The following link let's you practice this some more.

The picture I have included is of a crop circle in a farmer's field outside of Drayton Valley, Alberta. How would we determine the coordinates of the center of this circle if we wanted to write its equation?

Hint: It has something to do with a piece of technology that starts with a G!!!

you can always grid it

i also think if it was on a grid you could figure out its equation.
i hope the test today isnt hard mr.k! and if it is hopefully i will get this bonus mark!!

Hey Mr. K in this situation i think that you would have to put it on a grid because then you could find the radius and the center of the circle. I hope the test is pretty easy and that i don't forget everything by Monday.
