Question

14. 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)​

Answer 1

Answer:

yes it will

Step-by-step explanation:

Area of circle=πr²

314=3.14r²

r=10

radius of water sprinkler is 12

therefore entire garden can be waterd with sprinkler

Answer 2

Answer:

Area of the flower garden = 314 m square

Radius of the circular portion covered by the sprinkler = 12 m

∴ Area = 7πr square  = 3.14 × 12 × 12

= 3.14 × 144 m square  = 452.16 m square  

Since 452.16 m square  > 314 m square  

Yes, the sprinkler will water the entire garden.
