Answer:
Circumference ≅ 195 mm
Step-by-step explanation:
The circumference of a circle is equal to: [tex]2*\pi *radius[/tex]
Since [tex]Diameter = 2*radius[/tex] we can replace that in the circumference equation giving us:
[tex]Circumference = \pi *Diameter[/tex]
We know Diameter = 622 mm and pi = 3.14 so:
[tex]Circumference = \pi *Diameter = 3.14 * 622 mm = 195.308 mm[/tex]
