Grade 5 Circles

Step 1: Observe the diagram of the circle.

Step 2: The **Center** is the fixed point exactly in the middle of the circle. It is usually labeled with a point.

Step 3: A **Radius** is a line segment from the Center to any point on the boundary of the circle. Look for such a line segment.

Step 4: A **Diameter** is a line segment that passes through the Center and connects two points on the boundary of the circle. It is the longest chord. Look for such a line segment.

Step 5: Based on the labels in the diagram (assuming standard labels like O for Center, OA for Radius, BC for Diameter): Center: Point O Radius: Line segment OA (or any line segment from O to the boundary) Diameter: Line segment BC (or any line segment passing through O and connecting two points on the boundary)

Step 1: Understand the relationship between the radius and the diameter of a circle.

Step 2: The diameter of a circle is always twice the length of its radius. The formula is: Diameter = $2 \times$ Radius.

Step 3: The given radius is 5 cm.

Step 4: Substitute the value of the radius into the formula: Diameter = $2 \times 5$ cm.

Step 5: Calculate the diameter: Diameter = 10 cm.

Step 6: Therefore, if the radius of a circle is 5 cm, its diameter is 10 cm.

Step 1: Gather your tools: a pencil, a ruler, and a compass.

Step 2: Use the ruler to set the distance between the pencil tip and the compass point to 3 cm. This distance is the radius.

Step 3: Choose a point on your paper where you want the center of the circle to be. Place the sharp point of the compass on this point. This point is the center.

Step 4: Hold the compass by the top and rotate it carefully, keeping the sharp point fixed on the center. The pencil tip will draw the circle.

Step 5: You have now drawn a circle with a radius of 3 cm.
