saul85 [17]

Answer:

Final answer is slope = 0.73

Step-by-step explanation:

Given that an old house has a basement stairway.

Stairway has steps with 7.25 inch vertical risers and 10 inch horizontal treads. Now we need to find about what is the slope of the stairway.  Also round the answer to two decimal places.

slope=\frac{rise}{run}=\frac{7.25}{10}=0.725

Now round that value to two decimal places gives 0.73

Hence final answer is slope = 0.73

A silo consists of a cone stacked on top of a cylinder, where the radii of the cone and the cylinder are equal. The diameter of
Assoli18 [71]

Answer:

216π sq ft

Step-by-step explanation:

given that :

d = 12 ft => r = 12/2 = 6ft

h(cyl) = 10 ft

h(cone) = 8 ft

the surface area = ?

the solution :

the slant of cone = √r²+h²

= √6²+8²= √100 = 10 ft

the surface area of silo =

the lateral area of cone + the lateral area of cylinder + the base area

= π×r×slant + 2×π×r×h(cyl) + π×r²

= π×6×10 + 2×π×6×10 + π×6²

= 60π + 120π + 36π

= 216π sq ft
