Question

question 5 (multiple choice worth 1 points) (06 04 mc) around which line would the following cross - section need to be revolved to create a sphere? o y = 1 o x = 1 o y - axis o y = x

Explanation:

Step1: Recall sphere - formation principle

A sphere is formed by revolving a circle about its diameter. In a 2 - D coordinate system, if a circle is revolved about a line that passes through its center, a sphere is created.

Step2: Analyze the given circle and lines

The circle in the graph has its center on the y - axis. Revolving the circle about the y - axis (a line passing through the center of the circle) will create a sphere.

Answer:

C. y - axis
