Answer:
0.58 meters
Step-by-step explanation:
If he find several trees with circumferences greater than 1.8 meters.
C>1.8
Circumference of a circle =[tex]\pi d[/tex]
Therefore:
[tex]\pi d>1.8\\d>1.8 \div \pi\\d>0.57[/tex]
Therefore [tex]d\geq 0.58[/tex]
Therefore, the minimum diameter of one of the trees is 0.58 meters correct to 2 decimal places.
