Using the formula for the area of a circle:

A = πr^2

we have:

38.5 = πr^2

Solving for r, we get:

r^2 = 38.5/π

r^2 ≈ 12.25

r ≈ √12.25

r ≈ 3.5

So the radius of the circle is approximately 3.5 meters.

Using the formula for the circumference of a circle:

C = 2πr

we have:

C = 2π(3.5)

C ≈ 22

So the circumference of the circle is approximately 22 meters.
