# A circular flower bed is surrounded by a path 4 m wide. The diameter of the flower bed is 66 m. What is the area of this path?

Answer :

It is given in the question that,

Diameter of flower bed = 66 m

Radius of flower bed = = 33 m

Radius of flower bed and path together = 33 + 4 = 37 m

We know that,

Area of the circle = πr^{2}

∴ Area of flower bed and path together = 3.14 × 37 × 37

= 4298.66 m^{2}

Area of flower bed = 3.14 × 33 × 33

= 3419.46 m^{2}

Hence,

Area of path = Area of flower bed and path together - Area of flower bed

= 4298.66 – 3419.46

= 879.20 m^{2}
