Question 3 (6 points)
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?

a: π(2ft)2(8ft) + one over three π(2ft)2(9.5ft − 8ft)

b: π(8ft)2(2ft) + one over three π(2ft)2(9.5ft − 8ft)

c: π(2ft)2(8ft) + one over three π(9.5ft − 8ft)2(2ft)

d: π(8ft)2(2ft) + one over three π(9.5ft − 8ft)2(2ft)
