I don't understand, but if it's a cylindre with other cylindre inside, it's: R^2*h-r^2*h=(R^2-r^2)h Where R=6, r=2, h=5 Then: (6^2-2^2)*5=(36-4)*5=32*5=160

The volume of the big cylinder is pi (3)^2(5)=45 pi Volume of the little cylinder is pi (1)^2(5)= 5 pi Now subtract and get 40 pi and that is the remaining volume after you bore that hole in the middle.

i think the 6 and 2 refer to the diameters not the radius --> volume = 40pi

I think so too. That's why I used 3 for the radius of the big cylinder and 1 for the radius of the small cylinder.

Yes, you're right I have to look closer next time.
