Answer:

$c = 16.392\,\frac{USD}{ft^{2}}$

Step-by-step explanation:

The surface area of the cone shaped roof is:

$A_{s} = \pi\cdot (10\,ft)\cdot (6\,ft)$

$A_{s} \approx 188.496\,ft^{2}$

The cost of roofing per square feet is: (USD stands for US dollar)

$c = \frac{3089.76\,USD}{188.496\,ft^{2}}$

$c = 16.392\,\frac{USD}{ft^{2}}$
