Question

A circular flower garden has an area of 314 $m^2$ . A sprinkler at the centre of the garden can cover an area that has a radius of 12 $m$. Will the sprinkler water the entire garden? (Take $\pi$ = 3.14)

Answer 1

$Area = \pi r ^2$
= $3.14\times 12\times 12$
= $3.14\times 144$
= $452.16\; m^2$
Area of the circular flower garden = $314 \;m^2$

$Yes$, the sprinkler will water the whole garden.
