welshfella · Answer

first  find the area of the room  
area = (h/2)(a + b)    where h = height of the trapezoid and a and b are lengths of the opposite parallel sides

welshfella · Answer

the find the area covered by the cylinders  and subtract this from the area of the room

anonymous · Answer

Take 7.5 and divide it by 6 you get 1.25 so 1.25 of the floor is not covered.

welshfella · Answer

note you must convert the radii of the barrels to feet 
6 inches = 0.5 feet
