To find the area of the circle, we can use the relationship between the circumference \( C \) and the radius \( r \), as well as the formula for the area \( A \) of a circle.

The formula for the circumference of a circle is given by:

\[ C = 2\pi r \]

You provided:

\[ C = 12\pi \]

We can set these equal to each other:

\[ 2\pi r = 12\pi \]

To solve for \( r \), divide both sides by \( 2\pi \):

\[ r = \frac{12\pi}{2\pi} = 6 \]

Next, we can use the radius to find the area \( A \) of the circle. The formula for the area is:

\[ A = \pi r^2 \]

Substituting the value of \( r \):

\[ A = \pi (6^2) = \pi \times 36 = 36\pi \]

Thus, the area of the circle is \( 36\pi \).

The correct response is:

36π
