To find the area of the circle, we can start with the information given about the circumference.

The formula for the circumference \( C \) of a circle is:

\[ C = 2\pi r \]

where \( r \) is the radius. We are given that the circumference is \( 22\pi \) inches. Setting up the equation, we have:

\[ 2\pi r = 22\pi \]

We can now divide both sides by \( 2\pi \):

\[ r = \frac{22\pi}{2\pi} = 11 \text{ inches} \]

Now that we have the radius, we can find the area \( A \) of the circle using the formula:

\[ A = \pi r^2 \]

Substituting \( r = 11 \) inches into the area formula:

\[ A = \pi (11)^2 = \pi \times 121 \]

Now we substitute \( \pi \) with \( 3.14 \):

\[ A = 3.14 \times 121 \]

Now we calculate the area:

\[ A = 3.14 \times 121 = 379.94 \]

Thus, the area of the circle, expressed to the hundredths place, is:

\[ \boxed{379.94} \text{ square inches} \]
