Answer 2

Drawing a Circle and Calculating Diameter Length

To draw a circle with a radius between 2 cm and 3 cm and calculate its diameter length, we can follow these steps:

1. Draw a Circle with Radius Between 2 cm and 3 cm: - The radius of the circle should be greater than 2 cm and less than 3 cm. - The circle should be drawn with the specified radius.

2. Calculate the Diameter Length: - The diameter of a circle is twice the length of its radius. - Therefore, the diameter length can be calculated by multiplying the radius by 2.

Dividing the Diameter and Circle into Parts

To divide the diameter into parts and then the circle into 4 equal parts, we can follow these steps:

1. Divide the Diameter into Parts: - The diameter can be divided into equal parts by using a ruler or any measuring tool. - The length of the diameter should be measured accurately.

2. Divide the Circle into 4 Equal Parts: - To divide the circle into 4 equal parts, we can follow these steps: a. Start by drawing the diameter of the circle. b. From the center of the circle, draw two perpendicular lines to the diameter, dividing it into 4 equal parts. c. Each of these parts represents one-fourth of the circle.

Conclusion

By following these steps, we can draw a circle with the specified radius, calculate its diameter length, divide the diameter into parts, and then divide the circle into 4 equal parts.
