The radius of the circle below is $22 \mathrm{~mm}$. Calculate the area of the circle. Give your answer in $\mathrm{mm}^{2}$ to 1 d.p.

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
