Answer

Rounded to 1 decimal place, the area is $\boxed{1520.5}$ mm²

Steps

Step 1 ：Given the radius of the circle is 22 mm, we can calculate the area using the formula: Area = $\pi r^2$

Step 2 ：Area = $\pi (22)^2$ = 1520.53084433746 mm²

Step 3 ：Rounded to 1 decimal place, the area is $\boxed{1520.5}$ mm²
