Question 575071
V=volume (in cubic cm)
A=lateral surface area (in square centimeters)
h=altitude (in cm)
s=slant height (in cm)
r=radius of the base (in cm)
{{{V=(1/3)pi*r^2*h}}}, and with {{{h=15}}},
{{{V=(1/3)pi*r^2*15=5*pi*r^2}}}
{{{A=pi*r*s}}}
{{{V/A=2/1=5*pi*r^2/(pi*r*s)=5r/s}}} --> {{{2=5r/s}}} --> {{{2s=5r}}} --> {{{2s/r=5}}} --> {{{highlight(s/r=5/2)}}}
