Sure, let's find the area of the circle made by Nabina step-by-step.

To find the area of a circle, we use the formula:
\(\[ \text{Area} = \pi \times r^2 \]\)
where \(\( \pi \)\) (pi) is a constant approximately equal to 3.14159, and \(\( r \)\) is the radius of the circle.

Given:
- Radius of Nabina's circle, \(\( r = 20 \)\) meters

Using the formula:
\(\[ \text{Area} = \pi \times (20)^2 \]\)

Now, substituting the values:
\(\[ \text{Area} = \pi \times 400 \]\)

This results in:
\(\[ \text{Area} \approx 1256.6370614359173 \, \text{square meters} \]\)

So, the area of the circle made by Nabina is approximately \(\( 1256.64 \)\) square meters.
