Question

The answer for the bottom question need a fast quick answer

Answer 1

Area of a circle is

`A=\pi\cdot r^2`
`\begin{gathered} d=2r \\ d=22 \\ r=(22)/(2) \\ r=11 \end{gathered}`
`\begin{gathered} A=\pi(11)^2 \\ A=380.133ft^2 \end{gathered}`

The area of the garder is 380.13 square foots

If a square foot cost $ 1.25

`\begin{gathered} 1ft^2\to1.25\text{dollars} \\ 380.13ft^2\to x \\ x=(380.13ft^2\cdot(1.25dollar))/(1ft^2) \\ x=475.16\text{dollar} \end{gathered}`

To cover the garden they need to buy $475 in mulch
