Question

a circular flower bed is. surrounded by 4m wide path. The diameter if flower bed is 66m . Find the area of the path π =3.14

Answer 1

Radius of flower bed = 66/2 = 33m

Now, the path is 4 m wide, so radius of outer circle = 33 + 4 = 37 m

Area of the path = Area of circle surrounding the flower bed - area of flower bed.

=> Area of path = πR² - πr²

=> Area of path = π(R² - r²)

=> Area of path = π(R + r)(R - r)

Where, R = outer radius and r = inner radius

=> Area of path = 3.14(37 + 33)(37 - 33)

=> Area of path = 3.14(70)(4)

=> Area of path = 879.2 m²


Hope it helps dear friend ☺️✌️
