Sort the circles into columns that show their correct measurements using 3.14 for pi
Column 1:
1. Circle with a radius of 5 units
- Circumference = 2 * 3.14 * 5 = 31.4 units
- Area = 3.14 * 5 * 5 = 78.5 square units
2. Circle with a diameter of 10 units
- Circumference = 3.14 * 10 = 31.4 units
- Area = 3.14 * (10/2)^2 = 78.5 square units
Column 2:
3. Circle with a circumference of 20 units
- Radius = Circumference / (2 * 3.14) = 20 / (2 * 3.14) = 3.18 units
- Area = 3.14 * 3.18 * 3.18 = 31.7 square units
4. Circle with an area of 50 square units
- Radius = sqrt(Area / 3.14) = sqrt(50 / 3.14) = 4.48 units
- Circumference = 2 * 3.14 * 4.48 = 28.1 units
