Answer:
C
Step-by-step explanation:
The circumference of a circle can be found using:
[tex]c=\pi d[/tex]
We know that the circumference, or c is 5,871.8 We also know the pi is being rounded to 3.14, so we can substitute them in.
5,871.8=3.14d
We want to solve for d. To do this, we need to get d by itself. d is being multiplied by 3.14. To reverse this, divide both sides by 3.14
5,871.8/3.14=3.14d/3.14
The 3.14s on the right will cancel, leaving us with
1870=d
So, the diameter is 1870 mm, or choice C
