Answer:
[tex]c = 16.392\,\frac{USD}{ft^{2}}[/tex]
Step-by-step explanation:
The surface area of the cone shaped roof is:
[tex]A_{s} = \pi\cdot (10\,ft)\cdot (6\,ft)[/tex]
[tex]A_{s} \approx 188.496\,ft^{2}[/tex]
The cost of roofing per square feet is: (USD stands for US dollar)
[tex]c = \frac{3089.76\,USD}{188.496\,ft^{2}}[/tex]
[tex]c = 16.392\,\frac{USD}{ft^{2}}[/tex]
