Question

A pencil with pentagonal cross-section was sharpened using a pencil sharpener. Which of the options correctly represent(s) side view of the pencil?

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is B, D

To determine which options correctly represent the side view of a sharpened pencil with a pentagonal cross-section, consider the geometric transformation that occurs during sharpening. When a pencil is sharpened, the wooden casing is carved away, exposing the graphite core. This results in a pointed end. The side view of a sharpened pencil will typically show:

1. A pointed tip at one end where the core is exposed.
2. A tapered body leading up to the tip.

Now, examine the provided images:

Upon reviewing:

• The image with data-src-id="67160cc424f5e8d2e4b80968" correctly displays a tapered body leading to a pointed tip.
• The image with data-src-id="67160d0824f5e8d2e4b81282" also shows a similar tapered shape, suitable for a sharpened pencil.

Thus, the correct side views of the pencil are represented by these two images.
