To calculate the area of a circle, use the formula:

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

From the image, the radius $r = 7.3 \, \text{cm}$. Substituting this into the formula:

$\text{Area} = \pi (7.3)^2$

1. Square the radius: $7.3^2 = 53.29$

2. Multiply by $\pi \approx 3.1416$: $\text{Area} \approx 3.1416 \times 53.29 = 167.352$

Rounded to one decimal place: $\text{Area} \approx 167.4 \, \text{cm}^2$

Final Answer:

The area is 167.4 cm².
