The graphite in a pencil has a diameter of 1.5 millimeters and is surrounded by wood that is 2 millimeters thick.
What is the distance around the pencil? Use 3.14 for ππ. Round to the nearest millimeter.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

The diameter of the pencil is 1.5 + 2 + 2 = 5.5 millimeters.


The circumference is pi%2Ad = 3.14*5.5 millimeters.
