Firstly calculate the volume of the cylindrical hole of 4.12mm by the formula for volume of a cylinder
then calculate the volume of the cylindrical hole of diameter 4mm by the same formula.... then subtract the second answer from 1st answer... you will get the estimates amount of metal removed
Thanks!
