Circumference of a Circle = 2*pi*radius
Pi is an irrational number = 3.1416 can be approximated to 22/7
Thus Radius of the circle = Circumference/(2*pi)

Since C = 2 pi r, divide both sides by 2 pi and get r = C / (2 pi)

c=2 pi r
so r=c/ 2 pi

radius = circumference/(2*3.142), where we have used
pi=3.142 approximately or one could use (22/7) for it

c = 2 * pi * r
Therefore
r = c / (2 * pi)
