Question

A water sprinkler in a lawn sprays water as far as 5 m in all directions. Find the length of the outer adge of the wet grass taking
$\pi$
= 3.14

​

Answer 1

given:

5m in all directions

so diameter , d = 5m

therefore,

radius, r = 2.5 m

$length \: of \: outer \: boundary \: = \: circumference$

Formula :

$circumference = 2\pi \: r$

$= 2 \times 3.14 \times 2.5 \\ \\ = 15.7$

so, length of the outer boundary = 15.7 m
