Answer 1

Answer:

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.

Answer 2

To solve the problem we need to know about the rectangle.

Rectangle

A rectangle is a quadrilateral with opposite sides parallel and equal to each other. Also, all the angles of the rectangle are equal to 90°.

The correct option is c, which is A rectangle that is 5.4 in x 16.2 in.

Explanation

Given to us

the cylindrical container contains three tennis balls that are 5.4 inches in diameter which is lying on its side and passes through an x-ray scanner that scans from the top only.

Solution

As given, the cylinder is lying on its side, thus for the x-ray machine, the side will be the top of the cylinder. therefore, the cylinder will look like a rectangle, like the way it is shown below.

Therefore, the diameter of 3 balls will be the length of the rectangle while the width will be the diameter of 1 ball.

Hence, the correct option is c, which is A rectangle that is 5.4 in x 16.2 in.
