To calculate the area of a circle, you can use the formula:
\[
A = \pi r^2
\]
Where \( A \) is the area and \( r \) is the radius. If the radius \( r = 15 \) mm, the calculation would be:
\[
A = \pi (15 \, \text{mm})^2 = \pi (225 \, \text{mm}^2) \approx 706.86 \, \text{mm}^2
\]
So, the area of a circle with a radius of 15 mm is approximately \( 706.86 \, \text{mm}^2 \).
