Question

A circular flower garden has an area of 314m². A sprinkler at the centre of the garden can cover an area that has a radius of 12cm . Will the sprinkler water the entire garden.

Answer 1

Step-by-step explanation:

πr²=314

22/7×r²=314

r²=314×7/22

r²=100

r=√100

r=10

Radius of garden is smaller than the capacity of sprinkler.

Thus sprinkler will water the garden.

Answer 2

Answer:

Given : area = 314 m2

According to given condition 

π×r2= 314.

r2=100

∴r=10

Since Sprinkler can cover the garden with a radius of 12m as the radius of the circular garden is only 10m

∴ Sprinkler can water the entire garden.
