Question

Given below is a drawing on a sheet of paper. Make a cut along the solid arcs and fold the resulting semicircular rings at 90 degrees along the dotted lines. What is the number of raised semicircular rings after following these steps?

Hint:

When dealing with geometric folding problems, visualize the process step by step and count the resulting shapes or objects to ensure accuracy.

Answer 1

Correct Answer: 5

Step 1: Analyze the drawing.
The drawing shows several semicircular rings arranged in a sequence. The task is to make cuts along the solid arcs and fold the resulting semicircular rings at 90 degrees along the dotted lines.
Step 2: Count the rings.
After making the cuts and folding along the dotted lines, each of the semicircular rings will be raised at a 90-degree angle. By observing the drawing carefully, we see that there are 5 raised semicircular rings after following the steps.
Step 3: Conclusion.
Therefore, the total number of raised semicircular rings after following the steps is \( \boxed5 \).
