Answer:
She need 7 bags to cover the garden
Step-by-step explanation:
Diameter of circular garden = 16 feet
Radius of circular garden =[tex]\frac{16}{2} = 8 feet[/tex]
Area of circular garden =[tex]\pi r^2 = \frac{22}{7} \times 8^2 =200.96ft^2[/tex]
30 sq.feet covered by no. of bags = 1
200.96 sq.feet covered by no. of bags = [tex]\frac{200.96}{30}=6.69[/tex]
Hence She need 7 bags to cover the garden
