Question 317324
{{{V=pi*r^2*h=1.8}}}
{{{r^2*h=0.573}}}
Using thi equation, choose r and solve for h or choose h and solve for r.
.
.
.
As an example, 
Let {{{h=1}}},
{{{r^2*1=0.573}}}
{{{r=0.76}}}
So when the can has a height of 1 inch, the radius of the can should be 0.76 to hold 1.8 cubic inches.

Let {{{r=1}}},
{{{1^2*h=0.573}}}
{{{h=0.573}}}
So when the can has a radius of 1 inch, the height of the can should be 0.573 to hold 1.8 cubic inches.
