\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=\stackrel{altitude}{height}\\ \cline{1-1} r=3\\ h=9 \end{cases}\implies V=\cfrac{\pi (3)^2(9)}{3}\implies V=27\pi \implies V\approx 84.8

First, you set up the equation which would be 5y-8=3y-4.
                                                                             -3y       -3y
                                                                               2y-8= -4
                                                                                 +8    +8
                                                                                  2y=4
                                                                               divide by 2    
                                                                                   y=2
