![\bf \textit{volume of a cone}\\\\V=\cfrac{\pi r^2h}{3}~~\begin{cases}r=radius\\h=height\\\end{cases}\implies 3V=\pi r^2 h\implies \cfrac{3V}{\pi r^2}=h\\\\\\[-0.35em]\\\rule{34em}{0.25pt}\\\\\begin{cases}V=120\pi \\r=6\\\end{cases}\implies \cfrac{3(120\pi )}{\pi 6^2}=h\implies \cfrac{360\pi }{36\pi }=r\implies 10=r](/tpl/images/0060/2376/28407.png)
