6 is the 1st perfect number..............28 is the 2nd one....................with a radius of one............wrapping that around a circle.......................end to beg..........like pieces of string.......................strange that the number of times it wraps around........begins.....with a number.........6.28.................the connection of multiplication to addition....................1 and 2........like 1/2..............the critical line.....

The connection between multiplication and addition .........is deeper and more complicated than it seems...................


Answer: 2π (or about 6.283 pieces of string).

Radians Preferred by Mathematicians

Because the radian is based on the pure idea of "the radius being laid along the circumference", it often gives simple and natural results when used in mathematics.
