Question

The radius of a circle is 98 mm. What is the area of the circle? Write your answer to the hundredths place. Use 3.14 for π
.

Answer 1

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 \( \pi \approx 3.14 \), we can substitute these values into the formula:

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

First, calculate \( 98^2 \):

\[
98^2 = 9604
\]

Now, substitute back into the area formula:

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

Now, perform the multiplication:

\[
\text{Area} = 30638.56
\]

Thus, the area of the circle is:

\[
\text{Area} \approx 30638.56 \text{ mm}^2
\]

Therefore, the area of the circle, rounded to the hundredths place, is **30638.56 mm²**.
