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**.
