Hi Guys
It is normal for us Brits to round Pi up to 3.142 and then round up the
answer as well! hey it's close OK! <grin>

Subject: British Pie!
Hey, Im tripping over here.
>From Haynes & Workshop manual:
"
Bore 70.61mm
Stroke 81.28mm
Capacity: 1274.8 cc
"
everytime I calculate it I get 1273.1 ccs.
Are the british using some kind of different Pi? (3.14159265358979)
(Bore/2)squared X PI X stroke X 4 = displacement right?
(70.61/2)=35.305
35.305 squared = 1246.443025
1246.443025 X PI = 3915.81625
3915.81625 X 82.28 = 318277.5448372
318277.5448372 X 4 = 1273110.17934
1273110.17934 /1000 (convert to cc) = 1273.1101793 !!!
Dude... what am I doing wrong? am I incorrect in asuming that all 4 cly are
the same? or what?
Thanks
Toby
