QuestionThe volume and surface area of a cone are given, respectively, by the formulas $V=\frac{1}{3} \pi r^{2} h_{\text {and }}$ S.A. $=\pi r L+\pi r^{2}$.What expression represents the surface area-to-volume ratio for a right cone in simplest form. $\frac{3 L+r}{r h}$ $\frac{3 r L+\pi}{h}$ $\frac{3 L+J r}{r h}$ $3 r L+3 \pi$
