A cardboard tube that is used to ship posters is shaped like a cylinder. The radius
of the tube is 2.5 inches, and the height of
2
the tube is 36.5 inches.
What is the approximate volume of the tube
in cubic inches?

it's

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
