Question

match each diagram with the word it represents.
circumference
diameter
radius
area

Explanation:

1. The first diagram (dashed circle) represents the circumference as it shows the outer boundary (perimeter) of the circle.
2. The second diagram (filled purple circle) represents the area as it shows the region enclosed by the circle.
3. The third diagram (circle with a dashed line through the center) represents the diameter as the diameter is a straight line passing through the center, connecting two points on the circle.
4. The fourth diagram (circle with a dashed line from center to edge) represents the radius as the radius is a straight line from the center to the circumference.

Answer:

• Dashed circle (first diagram) → circumference
• Filled purple circle (second diagram) → area
• Circle with dashed line through center (third diagram) → diameter
• Circle with dashed line from center to edge (fourth diagram) → radius
