1.	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 sprinkler water the entire garden ? (Take π = 3.14)
Answer» Area of the circular flower garden = 314 sq.m Radius of the sprinker = 12m Area of the sprinkler = πr² = 3.14 × 12 × 12 = 452.16 sq.mt ∴ 452.16 > 314 ∴ Yes, the sprinkler water the entire garden.

Answer»

Area of the circular flower garden = 314 sq.m

Radius of the sprinker = 12m

Area of the sprinkler = πr² = 3.14 × 12 × 12

= 452.16 sq.mt

∴ 452.16 > 314

∴ Yes, the sprinkler water the entire garden.
