Hopefully, the light of imagination. Those crops are someone's livelihood. If you want to make grass circles in your own yard, that is one thing. But destroying farm crops is vandalism, which is a crime.
you use circles to make stuff round
The possibility exists that crop circles could be caused by some weather phenomena such as a small-scale circular storm- dust devils they are called. a whirlwind answer for a baffling problem. admittedly not all are caused by the winds. Some crop circles are made by humans. People use planks of wood and tie rope to the end of it, then they flatten out the crops with the wood. Thus making a crop cirlce.
i believe people use wooden boards to fold the plants in a pattern. check this link out: http://www.youtube.com/watch?v=pEAQ-d07HlE
Two circles.
Yes. Provided that the sides of the square are the same as the circumference of the circles.
Hemp.
they use protractors to measure circles
It make the crop grow immediately when u use instant growth on the crop...immediately after u plant the seeds..
I've seen this video on the show "UFOs", I don't know if it's real or not but it showed glowing orbs (UFOs) flying over a corn field I believe and the orbs just flew over the field and a perfect crop circle just formed in a matter of seconds... This happened in England like I said, I don't know if it's real.
A pair of compasses are use to construct circles and arcs of circles
The question is misguided. You do not use radius only on circles!
The name for the units scientists use for circles are degrees.
