Question

The radius of a circle is 19 centimeters. What is the circle's area?
Use ​𝜋 ≈ 3.14 and round your answer to the nearest hundredth.
square centimeters

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 \( r = 19 \) centimeters, and using \( \pi \approx 3.14 \):

\[
\text{Area} = 3.14 \times (19)^2
\]

First, calculate \( 19^2 \):

\[
19^2 = 361
\]

Now plug this back into the area formula:

\[
\text{Area} = 3.14 \times 361
\]

Now calculate \( 3.14 \times 361 \):

\[
3.14 \times 361 = 1134.94
\]

Now, rounding to the nearest hundredth, the area of the circle is:

\[
\text{Area} \approx 1134.94 \text{ square centimeters}
\]

So, the area of the circle is **1134.94 square centimeters**.
