A covered bridge in Vermont has the dimensions shown

What is the volume of the roof rounded to the nearest tenths?

The volume of the roof rounded to the nearest tenths is 2226.56 ft³

Step-by-step explanation:

We note that the shape of the cross section of the roof is that of a triangle, whereby the volume in this case is the product of the length of the roof and the area of the triangular cross section as follows;

Area of the roof triangular cross section =

Width of the roof, W = 14.25 ft

Height of the roof, h = 2.5 ft

∴ Roof cross sectional area =

Length of roof = 125 ft

Hence, volume of root = Roof cross sectional area × Roof length

∴ Volume of root = 17.8125 ft² × 125 ft = 2226.56 ft³

The volume of the roof rounded to the nearest tenths = 2226.56 ft³.

b. t=-25h+3

step-by-step explanation:

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
