Question 44476
The volume of a cylinder is given by:
{{{V = (pi)r^2h}}}
To write h as a function of r, you would solve the above equation for h, so:
{{{h(r) = V/(pi)r^2}}} and, since V = 100, then:
{{{h(r) = 100/(pi)r^2}}}

To graph this function, treat h as the dependent variable (sort of like y) and r as the independent variable (sort of like x), then graph it on an x-y coordinate graph.

The graph looks like this:
{{{graph(300,200,-5,5,-5,100,100/(3.14x^2))}}}
