Answer:

$V_{composite\: figure} =678.24\: in^3$

Step-by-step explanation:

For a single cylinder:

radius (r) = 3 in (Given)

height (h) = 8 in (Given)

It is given that: all the three cylinders are identical, means their radii and heights are equal.

Thus, the volume of composite figure will be equal to three times the volume of single cylinder.

$\implies V_{composite\: figure} =3(\pi r^2 h)$

$\implies V_{composite\: figure} =3(3.14\times (3)^2 \times 8)$

$\implies V_{composite\: figure} =3(226.08)$

$\implies V_{composite\: figure} =678.24\: in^3$
