Answer:
V = 402.12385mm
Step-by-step explanation:
When the diameter is 8mm, the radius is 4mm.
V = (π(4^2))8
V = (16π)8
V = (50.2654)8
V = 402.12385
V ≈ 402, 402.1, 402.12, 402.124
Answer:
I believe that it is the first one.
Step-by-step explanation:

Here's the solution ~
As we know, we can calculate the circumference of a circle in terms of its diameter as :

where, c = circumference and d = diameter
And also, circumference of circle is terms of radius (r) is :
