To solve this problem you must apply the proccedure shown below:
1. You must calculate the perimeter of the circle:
The radius of the circle in inches is:
[tex]radius=\frac{(10ft)(12in)}{1ft}=120in[/tex]
[tex]P=2\pi(radius)\\ P=2\pi(120in)\\ P=753.98in[/tex]
2. Now, you must divide the perimeter by the space between each flower to find the number of flowers needed, which you can call [tex]x[/tex]:
[tex]x=\frac{753.98in}{6in}=125.6=126[/tex]
The answer is: 126 flowers.
