A company that manufactures storage bins for grains made a drawing of a silo. The silo has a conical base, as shown below:

The figure shows a silo shaped as a closed cylinder with a conical end. The diameter of the silo is 4 ft, the length of the cyl

Which of the following could be used to calculate the total volume of grains that can be stored in the silo? (6 points)



A) π(2ft)2(10ft) + one over three π(13ft − 10ft)2(2ft)

B) π(10ft)2(2ft) + one over three π(13ft − 10ft)2(2ft)

C) π(2ft)2(10ft) + one over three π(2ft)2(13ft − 10ft)

D) π(10ft)2(2ft) + one over three π(2ft)2(13ft − 10ft)

Answer 1

Answer:

• C) π(2ft)2(10ft) + one over three π(2ft)2(13ft − 10ft)

Step-by-step explanation:

The volume is the combination of two volumes: cylinder and cone.

Cylinder volume:

• Vcyl = πr²h

Cone volume:

• Vcon = 1/3πr²h

Given:

• r = 4/2 = 2 ft
• h(cyl) = 10 ft
• h(con) = (13 - 10) ft

The volume is:

• π(2 ft)²*(10 ft) + 1/3π(2 ft)²(13 - 10) ft

Correct choice is C

Answer 2

Answer:

C) π(2ft)2(10ft) + one over three π(2ft)2(13ft − 10ft)
