Question

lin measured the diameter of a circle in two different directions. measuring vertically, she got 3.5 cm. measuring horizontally, she got 3.6 cm. explain some possible reasons why these measurements differ.

Explanation:

• Measurement Error: Tools might not be precise. For example, a ruler with worn - out markings.
• Human Error: Misalignment of the measuring tool. Like not placing the ruler exactly along the diameter.
• Tool Limitations: If using a non - digital tool (e.g., a simple ruler), it may not capture the exact value due to its least count.

Answer:

Possible reasons for the different measurements are measurement error (e.g., imprecise tools), human error (e.g., misalignment of the measuring tool), and tool limitations (e.g., non - digital tools with a larger least count).
