Answer:
Container  will have less label area than container
 will have less label area than container  by about
 by about  .
.
Step-by-step explanation:
A rectangular sheet of paper can be rolled into a cylinder. Conversely, the lateral surface of a cylinder can be unrolled into a rectangle- without changing the area of that surface. 
Indeed, the width of that rectangle will be the same as the height of the cylinder. On the other hand, the length of that rectangle should be exactly equal to the circumference of the circles on the top and the bottom of the cylinder. In other words, if a cylinder has a height of  and a radius of
 and a radius of  at the top and the bottom, then its lateral surface can be unrolled into a rectangle of width
 at the top and the bottom, then its lateral surface can be unrolled into a rectangle of width  and length
 and length  .
.
Apply this reasoning to both cylinder  and
 and  :
:
For cylinder  ,
,  while
 while  . Therefore, when the lateral side of this cylinder is unrolled:
. Therefore, when the lateral side of this cylinder is unrolled:
- The width of the rectangle will be  , while , while
- The length of the rectangle will be  . .
That corresponds to a lateral surface area of  .
.
For cylinder  ,
,  while
 while  . Similarly, when the lateral side of this cylinder is unrolled:
. Similarly, when the lateral side of this cylinder is unrolled:
- The width of the rectangle will be  , while , while
- The length of the rectangle will be  . .
That corresponds to a lateral surface area of  .
.
Therefore, the lateral surface area of cylinder  is smaller than that of cylinder
 is smaller than that of cylinder  by
 by  .
