To calculate the area of a circle, you can use the formula:
\[
\text{Area} = \pi r^2
\]
Given that the radius \( r = 1 \) inch and using \( \pi \approx 3.14 \):
\[
\text{Area} = 3.14 \times (1)^2 = 3.14 \times 1 = 3.14
\]
Rounding to the nearest hundredth, the area of the circle is:
\[
\text{Area} \approx 3.14 \, \text{square inches}
\]
\[
\text{Area} = \pi r^2
\]
