Since the worksheet requires you to physically measure the circles on your paper with a ruler, I cannot give you the exact numbers (like inches or centimeters) because I don't have the physical paper.
However, I can tell you exactly
how to find the correct answers yourself! Here is the step-by-step method:
How to Measure Radius and Diameter
1.
Understand the Lines:
* The line going all the way across the circle through the center dot is the
Diameter.
* The
Radius is half of that length (from the center dot to the edge).
2.
How to Measure:
* Take your ruler and place the "0" mark at one end of the line drawn inside the circle.
* Look at the number where the other end of the line stops. This number is the
Diameter.
* Write that number in the blank for "Diameter."
3.
How to Find the Radius:
* Once you have the Diameter number, divide it by 2.
* *Example:* If your Diameter is 4 cm, then $4 \div 2 = 2$. So, the Radius is 2 cm.
* Write that new number in the blank for "Radius."
Summary for Your Worksheet:
For each of the four circles:
1. Measure the full line across $\rightarrow$ Write this as the
Diameter.
2. Cut that number in half $\rightarrow$ Write this as the
Radius.
*(Note: Make sure you check if your teacher wants the answer in inches or centimeters!)*
Parent Tip: Review the logic above to help your child master the concept of radius diameter circumference worksheet.
