Cutting Cakes and Kissing Circles

To divide a cake into equal sized pieces most people use knife and mixture of luck dexterity. These attempts are often met with varying success. Through precise geometric constructions performed the replacing Euclid's straightedge without using compass we find methods for solving certain cake-cutting problems exactly. Since it is impossible to exactly bisect circular when its center not known, our need multiple cakes. Using three cakes present simple method bisecting each them or their centers. Moreover, given marked cut n size n=3,4 6. Our based upon by Steiner Cauer from 19th early 20th century.
