FULL GLASS
{{{v=h*pi*r^2}}}
{{{v=8*pi*(1.5)^2}}}


PART FULL GLASS
{{{V=12*pi*2.5^2}}}, capacity, but you want to know the difference between this and v.


You are looking for {{{highlight(V-v=12*pi*2.5^2-8*pi*1.5^2)}}} and simplification or even FACTORIZATION will be useful in solving this difference.
{{{highlight(V-v=12*pi*(5/2)^2-8*pi*(3/2)^2)}}}
PLEASE try to factor this on your way to computing this difference.</PRE>
