Question 1159518
<br>
All measurements are in centimeters, so we don't have to worry about units.<br>
Volume of each rod:<br>
{{{(pi)(r^2)(h)}}} = {{{(3.14)(4^2)(20)}}}<br>
Perform that calculation; then divide 28134.4 by the result to find the number of rods.<br>
(The given numbers are good; the result you will get if you do the calculations correctly is a whole number.)<br>
