The circumference of a circle is 19π m. What is the area, in square meters? Express your answer in terms of pi*π*.

To find the area of a circle given its circumference, you can use the following steps:

### Step 1: Recall the formulas
- The formula for the circumference of a circle is:
  \[
  C = 2\pi r
  \]
  where \( r \) is the radius of the circle.

- The formula for the area of a circle is:
  \[
  A = \pi r^2
  \]

### Step 2: Find the radius
Given the circumference \( C = 19\pi \) meters, you can solve for the radius \( r \):
\[
2\pi r = 19\pi
\]
Now, divide both sides by \( 2\pi \) to solve for \( r \):
\[
r = \frac{19\pi}{2\pi} = \frac{19}{2} = 9.5 \text{ meters}
\]

### Step 3: Calculate the area
Now that we have the radius, we can find the area \( A \):
\[
A = \pi r^2 = \pi (9.5)^2
\]
\[
A = \pi \times 90.25 = 90.25\pi \text{ square meters}
\]

So, the area of the circle is **90.25π** square meters.
