To find the area of a circle, you can use the formula:
\[ \text{Area} = \pi r^2 \]
where \( r \) is the radius of the circle. Given that the radius \( r = 98 \) mm and using \( \pi = 3.14 \), we can calculate the area as follows:
\[ \text{Area} = 3.14 \times (98)^2 \]
First, calculate \( 98^2 \):
\[ 98^2 = 9604 \]
Now, substitute this back into the area formula:
\[ \text{Area} = 3.14 \times 9604 \]
Next, perform the multiplication:
\[ 3.14 \times 9604 = 30130.56 \]
Thus, the area of the circle is approximately:
\[ \text{Area} \approx 30130.56 \text{ mm}^2 \]
Therefore, the area of the circle, rounded to the hundredths place, is:
\[ \boxed{30130.56} \text{ mm}^2 \]
