A number patter is a list of numbers that follow a certain pattern like 2,4,6,8,10 is a pattern of 2's
The number -5 is anything but natural number.
It is an integer (Z) ,a rational number (Q) and a real number (R) .
The formula is L = 2 pi r * (angle measure / 360). We have everything we need to solve this, the angle is 90 and the radius is 12: L = 2 pi (12) (90/360). Do the work inside the parenthesis first to get : L = 2 pi (12)(.25). Solving for L: L = 6pi
