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:

  • Radius \( r = 98 \) mm
  • \( \pi \approx 3.14 \)

Now, substitute the values into the formula:

\[ \text{Area} = 3.14 \times (98)^2 \]

First, calculate \( 98^2 \):

\[ 98^2 = 9604 \]

Next, multiply by \( \pi \):

\[ \text{Area} = 3.14 \times 9604 = 30117.56 \]

Thus, the area of the circle is approximately:

\[ \text{Area} \approx 30117.56 , \text{mm}^2 \]

So the area of the circle is 30117.56 mm².
