Answer:

17.03 meters

Step-by-step explanation:

The circumference of a circle:

[tex]C=2\pi r \mbox{ or }C=\2d[/tex]

where r is the radius and d is the diameter.

Given the diameter here, all you need to do is multiply it by pi:

[tex]\rightarrow C=\pi d\\\rightarrow C=(3.14159...)(5.42)\\\rightarrow C=17.0274...[/tex]

Rounded to 2 decimal places, you get 17.03 meters.
