Answer:
Radius of the area covered by the sprinkler at the centre of the garden (r) = 12 cm \[\therefore \] Area covered by the sprinkler at the centre of the garden \[=\pi {{r}^{2}}\] \[=\text{3}.\text{14(12}{{\text{)}}^{\text{2}}}{{\text{m}}^{\text{2}}}\] \[\text{= 452}\text{.16 }{{\text{m}}^{\text{2}}}(>31\text{4 }{{\text{m}}^{\text{2}}})\] Hence, the sprinkler will water the entire garden.
