Answer 2

Answer: The diameter of Eduardo's hair is greater than Orla's hair by 0.007 cm.

Explanation:

Given: The diameter of Orla's hair strand = 0.005 cm

The diameter of Eduardo's hair strand = 0.012 cm

Clearly ,
`0.012>0.005`

The difference between the diameters=
`0.012-0.005=0.007\ cm`

Thus, the diameter of Eduardo's hair is greater than Orla's hair by 0.007 cm.
