ANSWER
4 m
EXPLANATION
The circumference formula is,
[tex]C=2\pi r[/tex]Where r is the radius of the circle.
Solving for r,
[tex]r=\frac{C}{2\pi}[/tex]The circumference of the swimming pool is 25.12m. If we use 3.14 for π,
[tex]r=\frac{25.12m}{2\cdot3.14}=\frac{25.12m}{6.28}=4m[/tex]The radius of the swimming pool is 4 m.
