The circumference is defined as the border of a circle. The circumference would call the arc length of the circle, as if it were commenced up and straightened out to a line segment.
The formula of circumference are:
[tex]C = 2 \pi r[/tex]
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,
[tex]C = 2 \pi r\\\\C =2 \times 3.14\times 7.8 \text{meters}\\\\C =49(approx.)[/tex]
Therefore, the circumference of this swimming pool is 49 meters.
