given that
height of cylinder h =4 cm
radious=3 cm
thickness t=3mm
from the given information inner radious r =3 cm
outer radious R =3+0.3 cm=3.3cm
volume of the cylinder V =pi h(R2-r2)
V= (3.14)*4(3.32-32)
V=(3.14)*4*1.89
V=23.7384 cm3.
therefore the volume of silver needed tomake a napkin ring =23.7384 cm3.
