The image shows a problem involving circular objects, specifically clock faces, where you are asked to find the area and perimeter (circumference) of each circle. 

From the visible information, we can see the following:

- The first clock has a radius of **4 cm**.
- The second clock has a radius of **8 cm**.
- The third clock has a radius of **10 cm**.

To find the area and perimeter (circumference) of a circle, we use the following formulas:

- **Area**: \( A = \pi r^2 \)
- **Circumference** (Perimeter): \( C = 2 \pi r \)

Let me calculate these for each clock.

### First Clock (radius = 4 cm):
1. **Area**: \( A = \pi (4)^2 = 16\pi \approx 50.27 \, \text{cm}^2 \)
2. **Circumference**: \( C = 2 \pi (4) = 8\pi \approx 25.13 \, \text{cm} \)

### Second Clock (radius = 8 cm):
1. **Area**: \( A = \pi (8)^2 = 64\pi \approx 201.06 \, \text{cm}^2 \)
2. **Circumference**: \( C = 2 \pi (8) = 16\pi \approx 50.27 \, \text{cm} \)

### Third Clock (radius = 10 cm):
1. **Area**: \( A = \pi (10)^2 = 100\pi \approx 314.16 \, \text{cm}^2 \)
2. **Circumference**: \( C = 2 \pi (10) = 20\pi \approx 62.83 \, \text{cm} \)

Would you like me to break these calculations down further or provide more details?

Here are 5 related questions:
1. What is the formula for the area of a circle?
2. How does increasing the radius affect the area of a circle?
3. Can you explain why the circumference is directly proportional to the radius?
4. How would the area change if the radius were doubled?
5. What would the area and circumference be if the radius was 12 cm?

**Tip**: Always remember that the area of a circle grows much faster than the circumference as the radius increases because the area is proportional to the square of the radius.
