The circumference of a circle 5cm in radius is about 31.42cm

Pi times the diameter of a circle gives its circumference. Since the radius is 5 cm, the diameter is 10 cm, and pi x 10 cm is the answer, or 31.4159 cm.

21.99113 approximately... * * * * * Accurate to 5 decimal places but WRONG by a factor of 2. Circumference = 2*pi*radius so radius = 7 cm => circumference = 43.98 cm.

Circumference of circle: 2*pi*5 = 31.416 cm rounded to 3 decimal places

The radius of the circle works out as 5 units in length

I'm not sure what you mean. If the radius is 5, the circumference is 10pi. (about 31 and a half) If the circumference is 5, the radius is 5 divided by 2pi. (about four fifths)
