Best answer

Diameter of the flower bed = 66 m

Radius = 66/2 = 33 m

Area of the flower bed = πr2

= 3.14 × 33 × 33

= 3419.46 sq.cm

Radius of the flower bed with path = 33 + 4 = 37 ms.

Area of the flower bed with path 

= 3.14 × 37 × 37

= 4298.66 sq.cm

Area of the path = Area of the flower bed with path – Area of the flower bed

= 4298.66 – 3419.46

= 879.2 sq.mts
