To calculate the area of a circle, you can use the formula:
\[
\text{Area} = \pi r^2
\]
where \( r \) is the radius of the circle.
Given the radius \( r = 98 \) mm and using \( \pi \approx 3.14 \):
\[
\text{Area} = 3.14 \times (98)^2
\]
First, calculate \( (98)^2 \):
\[
(98)^2 = 9604
\]
Now, substitute back into the area formula:
\[
\text{Area} = 3.14 \times 9604
\]
Calculating this gives:
\[
\text{Area} = 30372.56 \text{ mm}^2
\]
So, the area of the circle is:
\[
\boxed{30372.56} \text{ mm}^2
\]
\[
\text{Area} = \pi r^2
\]
where \( r \) is the radius of the circle.
