In the same way that you would use any other ruler except that you use the centimetre scale.
You can guess, that's the only way.
Use the ruler to measure the size of the circle you want - this will be a line all the way across the whole circle. Then, measure a piece of string with the ruler -- make this half the size of the original line. Use a thumbtack to tack the string in the spot you want the middle of your circle. Use a bit of tape to tape the other end onto your pencil (don't wrap it around or you will end up with a smaller circle!) Gently move the pencil around the thumbtack to make your circle.
A broken ruler still has lines of measurement on it - it's just not as convenient as it was when it was whole. You measure the same way, by holding the ruler next to the item you're measuring and deciding which line it reaches to. With a broken ruler, you will probably have to measure one part at a time and add the measurements together.
use a ruler to measure the length. use a protractor to measure the angle of incidence. i dont think there is any other way to measure a ray. unless you are talking about the angle which you most likely arent since the question clearly states 'ray'.
you can't steal puffles, since clubpenguin is a safe site, there is no way they would encourage you to steal. the only way puffles can leave is if you don't take care of them and they return to the wild.

The easy way to find the length of a pencil is to use a ruler to measure it. A "small" ruler might not make it, but a "regular" one foot ruler will do the job nicely.
No it doesn't. Keeping jewelery anywhere makes it easy to steal. Robbers know to look in odd places and the best way to keep expensive jewelry safe is a safe or an anti-theft alarm system in your home.
There is no such way To double money, or clone items of the sort, infact there's no way of cheating at all in runescape, it's a player used scam, to get you to give them items or steal your account. If you see a cheat device being advertised, it will most likely steal you runescape account, play safe, be safe.
In What Way?
maybe steal and use thieving skill
One way you could go about doing this is to use a ruler or other measuring device.
Yes, provided you use it in a grown-up way.
No way people don't have the rights to steal but they just do it.
No.
no way
