Answer:
The volume of a cylindrical conduit,
where
is the inner radius,
is the outer radius, h is the length.
First of all, we would covert each parameter into centimeters.
length of the conduit, 
outer radius, 
inner radius, 
Insert the values in the volume formula,

Hence, the volume of metal in the conduit is 510. 12 cubic centimeters.
