To measure the size of a gear you can take out its circumference, radius or diameter and you can also count the number of teeth on a gear. If a gear has 12 teeth and if each teeth is 1 inch long then the circumference of the gear will be 2 inches long]]> 2017-03-14 11:48:23 UTC https://padlet.com/seesam/j12b0mdl2rzs/wish/159942868
