Pretty much a circle-a disc.
Area of disc: pi*6^2 = 36*pi square cm
The area of a disc of radius R units is pi*r^2 square units.
History has not recorded when the discus throw was invented but it is believed to have been begun by the ancient Greeks. The discus throw was an event of the ancient Olympic Games of Greece held in 776 B.C. The ancient discus was made of stone, iron, bronze, or lead, and was shaped like a flying saucer. The winner of the discus throw was awarded the disc as a prize for winning the event.
A few aircraft companies, such as Chance-Vought and Sikorsky, have built disc shaped flying vehicles. The main problem with such aircraft (similar to the flying wing) is that they are very unstable and need a lot of effort, and money, to keep them up in the air. It's probably better to build a remote controlled flying saucer aircraft model, than to try and build and fly a real disc shaped aircraft. For references see the Wikipedia article: Military disc shaped aircraft, and the 2007 book; Secret Projects: Flying Saucer Aircraft.
Flying saucers are real aircraft from the planet Earth. Charles Zimmerman is to the flying saucer what Jack Northrup is to the flying wing. Go to Wikipedia Military Disc Shaped Aircraft to read more about aircraft that are saucer shaped. The flying saucers as a spacecraft from another planet is science fiction. There is no known way to travel faster than light. A rocket ship that travels slower than the speed of light would take to long to travel in the universe.
Flying disc was created in 1948.
There were other disc being manufactured by many different names. Pluto Platter, Mars Platter and Flying Saucer were the names of the first disc manufactured by Wham-O, the company that would eventually call it a Frisbee
World Flying Disc Federation was created in 1985.
The duration of Flying Disc Man from Mars is 2.78 hours.
Flying Disc Man from Mars was created on 1950-10-25.
Brandon throws a flying disc with a force of 8 N. If the disc has an acceleration of 4 m/s2, what is the mass of the disc?
The government of the United States has tested military disc-shaped aircraft, such as the Avro Avrocar (a hovercraft aka air cushioned vehicle), the Chance-Vought V-173, and the uninhabited recon flying vehicle: the Sikorsky Cypher I. There is no credible evidence that they have ever found a vehicle that came from another planet.
