    1. 17 whole cans

    2. Yes, 38.65 in2 of metal

    Step-by-step explanation:

    First we need to find the surface area of the can.

    The base and the top of the can have a area of pi*r^2.

    If the radius is half the diameter, we have r = 3/2 = 1.5 inches, so:

    A1 = pi * 1.5^2 = 7.069 in2

    The side of the can has a area of pi*d*h. If the diameter is 3 inches and the height is 4.5 inches, we have:

    A2 = pi*3*4.5 = 42.412 in2

    So the total area of the can is:

    2*A1 + A2 = 56.55 in2

    To know how many cans we can make with 1000 in2 of metal, we just need to divide the total metal for the surface area of each can:

    number of cans = 1000 / 56.55 = 17.684 cans

    We can make 17 cans, and the metal left over is 1000 - 17 * 56.55 = 38.65 in2
