A small water silo has a diameter of 30 feet and a height of 60 feet. The clay model the engineers used only has a height of 10 inches with proportional volume. Determine the diameter of the model.

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

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
