Answer: The volume of shell is 12.8π mm².
Step-by-step explanation:
Since we have given that
Radius to the inside of the shell = 4 milimeters
Radius to the outside of the shell = 4.2 milimeters
Since r changes from 4 mm to 4.2 mm
so, 
As we know that
Volume of shell is given by


So, the volume of shell is 12.8π mm².
