Answer:
d = 6
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = πd ← d is the diameter
Given C = 6π, then
πd = 6π ( divide both sides by π )
d = 
← cancel π on numerator/ denominator
d = 6

The volume of a sphere is V=4/3*pi*r^3
Since pi=3.14 and r=20, we have:
V=4/3*3.14*20^3
V=4/3*3.14*8000
V=4/3*25120
V=33493.33333
So the volume is about 33493 1/3 mm^3
