Answer 1

The area \( A \) of a circle is calculated using the formula:

\[ A = \pi r^2 \]

Given that the radius \( r \) is 98 mm and using \( \pi \approx 3.14 \), we can substitute the values into the formula:

\[ A = 3.14 \times (98)^2 \]

First, calculate \( 98^2 \):

\[ 98^2 = 9604 \]

Now, substitute this value back into the area formula:

\[ A = 3.14 \times 9604 \]

Now, perform the multiplication:

\[ A = 3.14 \times 9604 = 30106.56 \]

Therefore, the area of the circle is:

\[ \boxed{30106.56} , \text{mm}^2 \]
