Answer:

8

Step-by-step explanation:

The lateral area of a cone is ...

LA = (π/2)ds

where d is the diameter, and s is the slant height.

The area of this tower roof is about ...

LA = (π/2)(12 ft)(13 ft) = 78π ft² ≈ 245 ft²

About 245/32 = 7.7 bundles of shingles will be required for coverage.

You should buy 8 bundles of shingles to cover the roof.
