To find the circumference and area of the circle, we use the radius $r = 6.6$ meters.

Circumference

The formula for the circumference $C$ of a circle is: $C = 2 \pi r$

Substitute $r = 6.6$ meters: $C = 2 \pi \times 6.6 \approx 41.5 \text{ meters}$

So, the circumference of the circle is approximately 41.5 meters.

Area

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

Substitute $r = 6.6$ meters: $A = \pi \times (6.6)^2 \approx 136.9 \text{ square meters}$

So, the area of the circle is approximately 136.9 square meters.
