A cylindrical ring of thickness 3.5mm.Each ring has internal diameter 14 mm and external diameter 16 mm.Taking pie=3.14 calculate the volume of maetla in single link chain,writing your answer correc to 3 significant figs.
Find the volume of a disk the diameter of the outer ring, and then the volume of a disk of the inner ring diameter, subtract them.
that should get you started.
I don't see how a ring can be a cylinder. If it is a cylinder bent into a circular ring, then the thickness should equal half the distance between inner and outer diameters, but it doesn't here.
