Question

A circular pond of diameter 38m is surrounded by a grass path of uniform width 2m . calculate the area of the path​

Answer 1

Step-by-step explanation:

we need to find the area of the path

So,

1. We have to find the area of the circular pond.
2. And again the area of the circle including the path of 2m wide.

Procedure :

Area of the circular pond :

where radius will be 38/2 or, 19m

So, area = πr²

= 3.14 × 19 × 19

= 1133.54m²

Now,

Area of the circle included the path :

where

radius is 19 + 2 = 21

So, Area = 22/7 × 21 × 21

= 1386m²

Now,

Area of the path :

Area including the path - Area of the circular pond

= 1386.00 - 1133.54

= 252.46m² ans.

Answer 2

Step-by-step explanation:

a circular pond of diameter=38

width=2m

circular of the path?

area=πr2

=3.14 ×19×19

=1133.54m2

radios is=19+2=21

so

area=22/7×21×21

1386m2

area of the path- area of circular pond

=1386.00-1133.54

=252.46m2
