the radius of a circular field is 20 metre inside its runs a path 5 M wide all around find the area of the path
Answers
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

Answer:
Step-by-step explanation:
Radius of the field (R) = 20 m
Width of the path = 5 m
Radius of inner part = (20-5) m
r = 15 m
Area of the path
= ar(bigger circle) - ar(smaller circle)
= πR² - πr²
= π(R² - r²)
= π(20² - 15²)
= π(400 - 225)
=(22÷7)(175)
=(22÷1)(25)
=22 x 25
=550 m²
Hence, area of the path is 550 m²
