Question

A cone shaped roof has a diameter of 12 feet a height of 8 feet and a slant of the roof is 10 feet if the roofing cost a total of $3089.76 how much does it cost per square feet

Answer 1

`c = 16.392\,(USD)/(ft^(2))`

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 = (3089.76\,USD)/(188.496\,ft^(2))`

`c = 16.392\,(USD)/(ft^(2))`
