<PRE><B>Question 81793</B>
Then determine the squares of roofing materials that would be needed to cover each surface.
Roof # 1. The cone-shaped part is 23ft with a radius of 8ft.
Area = (1/3)Bh
I assume the height of the cone is 23 ft.
=(1/3)(pi)(8^2)(23)
=1541.47
----------------------- 
 
Roof # 2 the cone-shape part is 12ft. with a radius of 9ft. find the answer for each roof. 
Area = (1/3)Bh
Area = (1/3)(pi)9^2
Area = 84.82 sq. ft.
