Question

the radius of a circular field is 20 m. inside it runs a path 5m wide all around.find the area of the path
( take π =22/7)​

Answer 1

Answer:

Step-by-step explanation:

Radius of circular field = 20m

As, we know area of circle is given by the formula → πr²

So, Area of circle = (22/7) (20)²

= (22/7)(400)

= 1257.14 m²

If the width of path is 5m then the radius of circle when we remove the path = (20-5)m

= 15m

Area of circle without path

= (22/7)(15)²

=( 22/7)(225)

=707.14 m²

So, The area of path will be →

Area of whole circle​ - Area of circle without the path

= 1257.14 - 707.14

= 550 m²

Answer → Area of the path is 550m²
