The formula of circumference are:

$C = 2 \pi r$

Where,

C = Circumference,

r = Radius

Computation of circumference of swimming pool:

According to the given information,

r = 7.8 meters.

Now, apply the given values in the above formula,

$C = 2 \pi r\\\\C =2 \times 3.14\times 7.8 \text{meters}\\\\C =49(approx.)$

Therefore, the circumference of this swimming pool is 49 meters.
