Explanation / Answer

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.
