Question

Jane has a circular garden with a diameter of 16 feet if one bag of fertilizer covers 30 ft.² how many bags will she need to cover the garden

Answer 1

She need 7 bags to cover the garden

Explanation:

Diameter of circular garden = 16 feet

Radius of circular garden =
`(16)/(2) = 8 feet`

Area of circular garden =
`\pi r^2 = (22)/(7) * 8^2 =200.96ft^2`

30 sq.feet covered by no. of bags = 1

200.96 sq.feet covered by no. of bags =
`(200.96)/(30)=6.69`

Hence She need 7 bags to cover the garden
