Question

A circular flower garden has an area of `314m^2.` A sprinkler at the centre of the garden can cover an area that has a radius of `12m.` Will the sprinkler water th entire garden ? (Take p`pi=3.14`)

Answer 1

Area covered by sprinkler, `A = pir^2`
`A = 3.14**12**12 = 491m^2`
As, `491m^2`(area covered by sprinkler) `gt 314m^2` (area of circular garden), it will water the entire garden.
