Wait a minute! Something's got to give. I think Rocky is talking about SAE inches and Matt is referring to metric inches.

Also, the circumference of a circle is given by pi X the diameter. So, 3.14 X 9" gives ~ 28 1/4" (metric or SAE). Based on that calculation I strongly recommend sending Llama a pair of Harris hose for in vivo consumer testing. I further suggest that Rocky send him a left sock of one color and Matt a right sock of another color in case he has in mind absconding to Scotland with his purloined hose. But, then again he already lives in the Highland(s), so perhaps that won't be necessary.

Glad to be of assistance.
