Question

match each diagram with the word it represents.
radius

diameter

circumference

area

Explanation:

Step1: Analyze the first diagram (dashed circle around a circle)

This represents the circumference, as the circumference is the distance around the circle (the dashed line traces the outer edge). So match the first diagram with "circumference".

Step2: Analyze the second diagram (filled pink circle)

This represents the area, as the area is the region inside the circle (the filled circle shows the inner region). So match the second diagram with "area".

Step3: Analyze the third diagram (dashed line across the whole circle, through center)

This represents the diameter, as the diameter is a straight line passing through the center, touching two points on the circle. So match the third diagram with "diameter".

Step4: Analyze the fourth diagram (dashed line from center to edge)

This represents the radius, as the radius is a straight line from the center to the circumference. So match the fourth diagram with "radius".

Answer:

1. First diagram (dashed circle) - circumference
2. Second diagram (filled pink circle) - area
3. Third diagram (dashed line across circle) - diameter
4. Fourth diagram (dashed line to center) - radius
