Acompany 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(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)
