Question

The radius of a circle is 18 inches. What is the circle's area?
Use ​𝜋 ≈ 3.14 and round your answer to the nearest hundredth.
square inches

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 \( r = 18 \) inches and using \( \pi \approx 3.14 \):

\[
\text{Area} = 3.14 \times (18)^2
\]

First, calculate \( (18)^2 \):

\[
(18)^2 = 324
\]

Now, multiply by \( 3.14 \):

\[
\text{Area} = 3.14 \times 324
\]

Calculating this gives:

\[
\text{Area} = 1,017.36
\]

So, the area of the circle is approximately

\[
\boxed{1017.36} \text{ square inches}.
\]
