Hello!
To find the diameter we can use the equation to find the circumference
[tex]C = 2 \pi r[/tex]
C is circumference
r is radius
Put in the values we know and 3.14 for pi
[tex]6261.16 = 2 * 3.14 * r[/tex]
Multiply
[tex]6261.16 = 6.28 * r[/tex]
Divide both sides by 6.28
997 = r
the diameter is double the radius
997 * 2 = 1994
The answer is 1994mm
Hope this helps!
