This is your answer.....
Given :::
Diameter = 42 m.
Radius = D/2 = 21 m.
We have to find the length of circular garden.
So....
We will obtain perimeter....
P of Circle = 2 × 22/7 × 21
= 6 × 22
= 132 m.
Hence the length of boundary is 132 m.
But the gardener takes three round od the fence...
So length of wire needed = 3× 132
= 396 m.
Hence the length of wire needed is 396 m
Hope it helpa
