​

Answer 1

Step-by-step explanation:

Radius of

flower bed 

=

33 m

Radius of

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

Area of

flower bed and path together = 3.14 × 37 × 37 = 4298.66

m2

Area of

flower bed = 3.14 × 33 × 33 = 3419.46 m2

Area of

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

bed

= 4298.66 − 3419.46 = 879.20 m2
