Answer:
5
Step-by-step explanation:
In order to figure out average, we need to add up all the numbers. So adding 2, 4, 5, 6, and 8 gives us 25. We now divide that total by the total number of terms we used to reach 25. So since we had 5 numbers, we divide 25 by 5 to get an average of 5.
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
