If a circle has a circumference of 16 cm then the radius is about: 2.546 cm
A circle with a radius of 16 inches has a circumference of 100.53 inches.
radius = 16/(2*pi)
the circumference of any circle is 2PIr or two times PI(3.14) times the radius (in this case, 16). do the math.
About 100.53 feet.
The radius of a circle is circumference/2 pi .
A circle with a radius of 16 inches (32/2) has a circumference of 100.53 inches.
Circumference of the circle: 2*pi*8 = 16*pi m
