The problem in the uploaded image requires calculating the area of a circle, given its radius $r = 11 \, \text{cm}$. The formula for the area of a circle is:

$\text{Area} = \pi r^2$

Step-by-step Calculation:

1. Substitute $r = 11 \, \text{cm}$ into the formula: $\text{Area} = \pi (11)^2$

2. Square the radius: $11^2 = 121$

3. Multiply by $\pi$ (using $\pi \approx 3.14159$): $\text{Area} \approx 3.14159 \times 121 = 380.1327 \, \text{cm}^2$

4. Round to 1 decimal place: $\text{Area} \approx 380.1 \, \text{cm}^2$

Final Answer:

The area of the circle is 380.1 cm² (to 1 decimal place).
