A cylindrical container that contains three tennis balls that are 5.4 inches in diameter is lying on its side and passes through an x-ray scanner that scans from the top only. What outline will appear on the x-ray screen, and what are the dimensions?

cylindrical container with three spheres side by side so that the spheres are laying horizontally

A circle with a diameter of 5.4 in
A circle with a diameter of is 10.8 in
A rectangle that is 5.4 in x 16.2 in
A rectangle that is 10.8 in x 16.2 in
can you help me

Option (1). A circle with a diameter of 5.4 in.

Step-by-step explanation:

It's given in the question that a cylindrical container contains 3 tennis balls.

If this container passes through an x-ray scanner that scans along the length of the cylinder, outline will appear on the x-ray screens as figure (1)

But the x-ray scanner that scans from the top only. So, the outline will appear on the screen as a circle with a diameter of 5.4 in. as in figure (2).

Option (1) will be the answer.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
