Question

a water sprinkler in a lawn sprays water as far 5 m in all direction .find the length of the outer edge of the wet grass taking pie =3.14 ​

Answer 1

Answer:

5 m in all directions

so Diameter = 5

radius = 2.5

length of outer boundary = circumference

so l = 2 π r

= 2 X 2.5 X 3.14

=15.7

Answer 2

Answer:

Given

radius =5m

Step-by-step explanation:

5m in all directions

so,radius = 5

length of outer bountry = circumstance

= 2πr

= 2×5×3.14

= 31.4m

Length of outer edge of wet grass = 31.4
