Question

The radius of a circle is 1 centimeter. What is the circle's area?
r=1 cm
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:

\[
\text{Area} = \pi r^2
\]

Given that the radius \( r \) is 1 centimeter, you can substitute this value into the formula. Using \( \pi \approx 3.14 \):

\[
\text{Area} = 3.14 \times (1)^2
\]

Calculating this gives:

\[
\text{Area} = 3.14 \times 1 = 3.14
\]

Thus, the area of the circle is \( 3.14 \) square centimeters.

Rounded to the nearest hundredth, the area is:

\[
\text{Area} = 3.14 \, \text{square centimeters}
\]
