The fellow is also wrong. 45/60 = .75. 100/.75 = 133.333.... If rounded to 133, you get 45.11278195---- Still, using Tony's multiple method, 400 dots would work fine. It would be a large disk but it would work. Dwight -----------Reply: If you're saying that he's wrong, that it's not 45.11 but should be 45.11278195 then I can see why you & I are arguing over whether 300/50 = 360/60 or 360/60 = 300/50... BTW, you're wrong; it's 45.1127819548872180451127819548872 ;-) m
