You do not, but in the world of science publication, if it was something key, you would have to prove it. Such as saying you made a compound, you have to produce all the spectra. In this case, as it is stated as 14.0cm, it is likely she did not round up. You round up to get rid of figures, not to replace the significant figure with a zero. If she quoted as 14cm, there would be more suspicion.

Length of unsharpened pencil is measured in cm . km is a bigger quantity.

You can use the circumference of the pencil and the circumference formula to find the radius. Set the measured circumference equal to 2pi*radius and solve. I measured it to about .75 of an inch, so: .75=2pi*radius r=.75/2pi
