To calculate the approximate area of a circle given the radius \( r \), you can use the formula:
\[
\text{Area} = \pi r^2
\]
If \( r = 15 \) mm, then:
\[
\text{Area} = \pi (15 \, \text{mm})^2
\]
\[
\text{Area} = \pi \times 225 \, \text{mm}^2
\]
\[
\text{Area} \approx 3.14159 \times 225 \, \text{mm}^2
\]
\[
\text{Area} \approx 706.86 \, \text{mm}^2
\]
Therefore, the approximate area of a circle with a radius of 15 mm is about **706.86 mm²**.
