Question

​Sheet copper costs $8.83 per square foot. How much did it cost to cover this roof in copper if the diameter of the base is 16 feet and the slant height is 12 feet? Use 3.14 for pi.

a
Cost = 2,000.72
b
Cost = $2,484.62
c
Cost = $2,925.72
d
Cost = $2,661.72

Answer 1

it cost approximately to $2,661.72

STEP-BY-STEP EXPLANATION:

radius (r)= d/2= 16/2=8ft

Slant height (l)=12ft

Actual surface area = πrl

=3.14×8×12

=301.44m^2

Total cost of roofing = $(301.44×8.83)

=$2,661.72
