Final answer:

Rotating a vertical strip around the y-axis creates a cylinder with a radius equal to the distance between the y-axis and any point on the vertical strip.

Step-by-step explanation:

When rotating a vertical strip around the y-axis, you create a cylinder. The radius of the cylinder can be determined by the radius of the vertical strip.

Let's consider a point on the strip that is a distance 'r' away from the y-axis. When this point rotates around the y-axis, it traces out a circle with radius 'r'. Therefore, the radius of the cylinder is equal to the distance between the y-axis and any point on the vertical strip
