A circular flower garden has an area of 314 m2. 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 π =3.14]
Circular area by the sprinkler = πr 2
= 3.14 x 12 x 12
= 3.14 x 144 = 452.16 m2
Area of the circular flower garden = 314 m2
Since Area of circular flower garden is smaller than area by sprinkler. Therefore the sprinkler will water the entire garden.
