Question

question 2 (05.04 mc) a cylindrical container that contains three tennis balls that are 2.7 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? a circle with a diameter of 2.7 in a circle with a diameter of 8.1 in a rectangle that is 5.4 in x 8.1 in a rectangle that is 2.7 in x 8.1 in

Explanation:

Step1: Analyze the shape of the cross - section

When a cylinder lying on its side is scanned from the top, the cross - section shape is a rectangle. The diameter of the tennis ball gives the width of the rectangle, and the sum of the diameters of the three tennis balls gives the length of the rectangle.

Step2: Calculate the dimensions of the rectangle

The diameter of each tennis ball is \(d = 2.7\) inches.
The width of the rectangle \(w=2.7\) inches.
The length of the rectangle \(l = 3\times2.7=8.1\) inches.

Answer:

A rectangle that is \(2.7\) in \(×8.1\) in (Option A)
