Answer 1

To find the radius of each circle given its diameter, the formula used is:

\[
\text{Radius} = \frac{\text{Diameter}}{2}
\]

Now, let's calculate the radius for each diameter:

1. **Diameter = 40.67 cm**:
\[
\text{Radius} = \frac{40.67}{2} = 20.335\ \text{cm} \approx 20.34\ \text{cm}
\]

2. **Diameter = 24.43 cm**:
\[
\text{Radius} = \frac{24.43}{2} = 12.215\ \text{cm} \approx 12.22\ \text{cm}
\]

3. **Diameter = 18.95 cm**:
\[
\text{Radius} = \frac{18.95}{2} = 9.475\ \text{cm} \approx 9.48\ \text{cm}
\]

4. **Diameter = 17.34 cm**:
\[
\text{Radius} = \frac{17.34}{2} = 8.67\ \text{cm}
\]

Now, we can match them with their appropriate values:

- Diameter = 40.67 cm → Radius = **20.34 cm**
- Diameter = 24.43 cm → Radius = **12.22 cm**
- Diameter = 18.95 cm → Radius = **9.48 cm**
- Diameter = 17.34 cm → Radius = **8.67 cm**

In summary:

1. 40.67 cm → 20.34 cm
2. 24.43 cm → 12.22 cm
3. 18.95 cm → 9.48 cm
4. 17.34 cm → 8.67 cm
