A grain silo is approximately 85% full. A 55 lb sack of grain measures 2 cubic feet.
erastova [34]

Answer:

Option A . 1708 bags

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the volume of the silo

The volume of the silo is equal to the volume of a cylinder plus the volume of a cone

so

V=\pi r^{2}h_1+\frac{1}{3}\pi r^{2}h_2

we have

\pi =3.14

r=16/2=8\ ft ---> the radius is half the diameter

h_1=16\ ft

h_2=12\ ft

substitute

V=(3.14)(8)^{2}(16)+\frac{1}{3}(3.14)(8)^{2}(12)

V=3,215.36+803.84=4,019.2\ ft^3

Remember that

The silo is approximately 85% full

so

The volume of grain in the silo is

0.85(4,019.2)=3,416.32\ ft^3

step 2

Find the number of bags of grain

Divide the volume of grain in the silo by the volume of one sack

3,416.32/2=1,708\ bags
