The expected diameter is 70 cm.
It is acceptable for the diameter to be within 0.02 cm of the expected value.
Therefore the acceptable values for the diameter, d, are
[tex]d \pm 0.02 = 70[/tex]
The minimum acceptable value of d is obtained from
d + 0.02 = 70
d = 69.98 cm
The maximum acceptable value of d is obtained from
d - 0.02 = 70
d = 70.02 cm
Answer:
Minimum acceptable diameter = 69.98 cm
Maximum acceptable diameter = 70.02 cm
