What is 'perimeter'?

I selected the round face of a cylinder and measured it.  I got several values, one of which was 'perimeter'.  While I understand the concept of a perimeter, I do not understand what this value represents.  How can an 8" diameter x 24" long roller have a perimeter of 72.76"?  Even in the cross section, I would expect it to be 64".  What is being measured to get 72.76"?
