It looks like you've uploaded a worksheet titled
"Radius and Diameter" that includes several circles with labeled measurements. The task appears to be identifying whether the given line segment in each circle is the
radius or the
diameter, and possibly calculating missing values.
Since I can't view images directly, I’ll guide you through how to solve such problems step by step based on common formats of this type of worksheet.

🔍 Understanding Radius and Diameter
-
Radius (r): A line segment from the
center of the circle to any point on the edge.
-
Diameter (d): A line segment that passes through the
center and connects two points on the edge. It's
twice the radius:
$$
d = 2r \quad \text{or} \quad r = \frac{d}{2}
$$

✔ How to Solve Each Problem
For each circle on the worksheet:
1.
Look at the line drawn:
- Does it go from the
center to the edge? → That’s the
radius.
- Does it go from one edge through the center to the other edge? → That’s the
diameter.
2.
Label accordingly:
- Write “radius” or “diameter” next to the line.
- If a number is given, use the relationship $ d = 2r $ or $ r = \frac{d}{2} $ to find the missing value.

📌 Example Problems (Typical Worksheet Format)
Let’s assume the worksheet has something like this:
#### Circle 1:
- Line from center to edge: length = 5 cm
→ This is the
radius.
#### Circle 2:
- Line across the circle passing through the center: length = 10 cm
→ This is the
diameter.
So, radius = $ \frac{10}{2} = 5 $ cm.
#### Circle 3:
- Line from center to edge: no label
→ Label as
radius, and if diameter is given elsewhere, compute it.

✏️ Common Tasks on Such Sheets
1.
Identify: Is the line a radius or diameter?
2.
Calculate: Find the missing radius or diameter.
3.
Match: Given radius, find diameter, or vice versa.

🔧 Tips for Accuracy
- Always check if the line goes through the
center.
- The
diameter is always
longer than the radius.
- Use the formula:
$$
\text{Diameter} = 2 \times \text{Radius}
$$

💡 Final Answer Format (Example)
If a problem says:
> "The line from the center to the edge is 7 cm. What is the diameter?"
Answer:
$$
\text{Diameter} = 2 \times 7 = 14 \text{ cm}
$$
And label:
This is a radius.

If you can describe the specific circles or provide the measurements from the image (e.g., "Circle A has a line from center to edge labeled 6 cm"), I can help you solve them one by one!
Otherwise, just apply these rules to each circle on your worksheet. Let me know if you'd like me to walk through a specific example!
