Question 1020168
h, length of cone
r, radius of bottom or base
pi for abourt 3.14


{{{2pi*r=17pi}}}
{{{r=(17pi)/(2pi)}}}
{{{highlight_green(r=17/2)}}}


{{{h=-5+2r}}}
{{{h=2r-5}}}
{{{h=2(17/2)-5}}}
{{{h=17-5}}}
{{{highlight_green(h=12)}}}


You have two quantities now known, and the question is, find the volume of the cone.   Volume {{{(1/3)h*pi*r^2}}}.
