Modern metal cans, like the one shown, are usually made from steel, and
then covered with a thin layer of tin.
a. Write an inequality representing the amount of sheet metal that can be
used to make a can that is 10 cm tall
b. Graph the inequality
Explain how the graph can be used to determine the minimum amount of metal required for cans of various radii.
I only need help on a and b. I should be fine for B
