Question

A circular garden of radius 10m has a
straight line fence between the two
points on the boundary of the garden.
The fence lies inside the garden arena.
This fence separates the walking area
which is a small region from the plants.
The fence is at a distance of 6 m from
the centre of the garden. What is the
walking area in m?? It is given that cos
3
53° = 5.​

Answer 1

Answer:

Step-by-step explanation:

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
