Answer
$113.1\; in^3$.
Work Step by Step
Diameter of the cylindrical rod is $d = 3.0\; in$.
Radius $r=\frac{d}{2}$.
$r=\frac{3.0\; in}{2}$
Length $h=16\;in$.
The formula for volume is:
$V=\pi r^2 h$
Plug all values.
$V=\pi (\frac{3.0\; in}{2})^2 (16\; in)$
Simplify (rounded to the nearest one decimal).
$V=113.1\; in^3$.
