How can my answer be incorrect if I haven't even figured it out yet??

The volume of a cylinder is (pi) (radius²) (height, length, or depth).

The pool's diameter is 8m, so its radius is 4m.

The volume of the pool is (pi) (4m) ² (1.6 m) = 25.6 pi m³.

Filling it at the rate of 11 m³/hr, it will take

(25.6 pi / 11) = 7.308 ... hours to fill it to the brim.

Rounded to the nearest hour, that's 7 hours.
