Question

a circular flower bed is surrounded by a path 5 m wide . the dia meter of flower bed is 65 m . what is the area of the path​

Answer 1

Diameter of flowerbed=65 m

Radius=65/2

Its area=(22/7)x(65/2)x(65/2)

Diameter of flowerbed+path=65+5+5=75 m

Radius=75/2

Its area=(22/7)x(75/2)x(75/2)

Area of path=Total area-Ar of flowerbed

={(22/7)x(75/2)x(75/2)}-{(22/7)x(65/2)x(65/2)}

=1100 sq m

Answer 2

solution:

65+5=70/2=35

the area of whole circle=πr²

=22/7×35×35

=3850m²

diameter/2=65/2=32.5

the area of circular flower =πr²

=22/7×32.5×32.5

=3319.64m²

the area of whole circle - the area of circular flower bed =the area of path

3850-3319.64=530.36m²ans

I hope! I have helped you.
