Question

Hello I'm working on some homework practice questions and would like some help thank you

Answer 1

Given:

Radius of flower garden is 17yd.

Radius of outer edge is 20 yd.

Required:

To find the number of bags.

Step-by-step explanation:

The are of the garden is

`\begin{gathered} A=\pi*17^2 \\ =3.142*17*17 \\ =908.038 \end{gathered}`

The area of the outer ring is,

`\begin{gathered} A=\pi*20^2 \\ =\pi*20*20 \\ =1256.8 \end{gathered}`

The path area= overall area- garden area

`\begin{gathered} A=1256.8-908.038 \\ =348.762 \end{gathered}`

Find the number of bag of sand required

`\begin{gathered} =(348.762)/(2) \\ =174.381 \\ \approx174 \end{gathered}`

Final Answer:

174 bags required.
