Question 893336
You can find the formula for the volume of a cylinder, likely the shape of the can, in your instruction book
or in another good source.


Let h = height of (new) can
r = radius of can


{{{v=h*pi*r^2=375}}}


Old Can:  {{{v=19.1*pi*(2.5)^2=375}}}, good.


New Can: {{{h*pi*(3.5)^2=375}}}
{{{h=375/(3.5^2*pi)}}}
{{{h=9.744}}}
{{{highlight(9.7*cm)}}}, for the same accuracy as the other values.
