Question

The ideal diameter of a piston for a car engine is 90.000 mm. The actual diameter can vary from the ideal by at most 0.008 mm. What is the range of acceptable diameters for the piston?

Answer 1

(89.992, 90.008)mm

Answer 2

How did you solve that?

Answer 3

Subtract .008 from 90.000 and you get the minimum, add .008 to 90.000 and yo uget the maximum

Range = (least possible, greatest possible)
so = (90.000 - .008, 90.000 + .008)
= (89.992, 90.008)
