Question

The radius of a circle is 8 kilometers. What is the circle's area?
Use ​𝜋 ≈ 3.14 and round your answer to the nearest hundredth.
square kilometers

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. In this case, the radius \( r \) is 8 kilometers.

Using \( \pi \approx 3.14 \), we can calculate the area:

\[
\text{Area} = 3.14 \times (8)^2
\]

Calculating \( (8)^2 \):

\[
(8)^2 = 64
\]

Now, substituting back into the area formula:

\[
\text{Area} = 3.14 \times 64
\]

Calculating \( 3.14 \times 64 \):

\[
3.14 \times 64 = 200.96
\]

Thus, the area of the circle is approximately:

\[
\boxed{200.96} \text{ square kilometers}
\]
