A cylinder's volume,
The width of the rectangle, which forms the circumference,
graph{x+y=12 [-2.49, 25.99, -1.51, 12.74]}
The graph shows possible lengths for the sides of the rectangle if they must add up to 12 inches (
At what point along that curve is
graph{(12x-x^2)/(4pi) [-0.89, 13.35, -1.027, 6.1]}
Since
