Part A.
In the picture, we can see that it has a circular base and from it it goes right with the same shape for each section, so this is a prism. Since its base is a circle, this is close to a cylinder.
Part B.
The diameter of the base and the length is shown, so we just need to draw a cylinder and put these measures:
The net of a cylinder has the two circles of the base and the middle part is unfolded to form a rectangle:
Part C.
The amount of plastic they will need corresponds to the surface area of the cylinder, and the net draw unfold the shape into a 2 dimensional draw, so we can use it to determine the surface area of the cylinder, which will lead us to the amount of plastic needed.
