To calculate the area of the circle with a radius of 22 mm, we can use the formula for the area of a circle:

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

Where:

• $\pi \approx 3.1416$
• $r$ is the radius, which is 22 mm.

Now, substituting the values:

$\text{Area} = \pi \times (22)^2 = 3.1416 \times 484 = 1520.531 mm^2$

Rounding the answer to 1 decimal place:

$\text{Area} \approx 1520.5 \, \text{mm}^2$

So, the area of the circle is approximately 1520.5 mm².
