"The chemical is dispensed to completely fill 25 identical cylindrical containers"
So obviously the volume of each is 1/25 of the whole volume, right? So you know V for one of these cylinders.
"each with a radius of 5 in"
V = pi*r^2*h
<span>You know V. You know r. Plug them in. Solve for h. Should take one line.
</span><span>235,500 /25 = 9420 is the volume of 1 cylinder.
</span>h <span>=</span><span>V/</span><span>π</span><span>r</span><span>2</span><span>
</span>h ≈119.94
If you expand, the answer is -12+2x
