Answer:
The cylinder has the same radius as the cans, but has a height twice as high.
Step-by-step explanation:
As you can see in the question above, a student stacked two cans, forming a cylinder.
In order for the cans to be stacked, to form a perfect cylinder, we can conclude that both cans have the same radius and the same height. When placed on top of each other, the formed cylinder is twice the size of the cans alone, however, the radius is not changed and the cylinder has the same radius as the cans.
