: A dull pencil lead in your compass makes it hard to be precise.

To solve exercise on page 137 of the Grade 5 Mathematics textbook (Vilenkin), you need to work with geometric tools to construct a circle. This task is part of the chapter "Circle and Disk". Step-by-Step Solution

: Open your compass so the distance between the needle and the lead is exactly 2 cm .

: Light pressure is all you need to create a clean line.

In 5th grade math, you move from basic arithmetic into early geometric classification. Learning to draw a circle with a specific radius (like the 2 cm radius in this problem) helps you understand the relationship between a center point and the points on the boundary. Pro-Tips for Success:
