Question

area of a circular garden is 160m² . a sprinkler at the centre of the garden can cover an area that has a radius of 7 cm. will the sprinkler water the entire garden ?

Answer 1

Answer:

no,we need around total 10 sprinkler to water the entire 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.
