Question

the answer is in the picture and when you get the answer can you just give it to me

Answer 1

First, we need to find the circular area. Since the radius is 5 feet, the circular area is given by

$\begin{gathered} A_c=\pi r^2 \\ A_c=3.1416(5^2) \\ A_c=78.54ft^2 \end{gathered}$

We know that 1 bag covers 5x3=15 square feet, then the ratio Circular area to bags is

$\text{ratio}=\frac{circular\text{ area}}{\text{bag}}=\frac{78.54}{15}=5.236$

Therefore, by rounding up to the next integer, the answer is 6 bags.
