A company that manufactures storage bins for grains made a drawing of a silo. The silo has a conical base, as shown below.
8 ft
9.5 ft
Which of the following could be used to calculate the total volume of grains that can be stored in the silo?
Om(2m)²(8)+m(2m)²(9.5m-8m)
Om(8m) (2m)+m(2)²(9.5-8m)
Om(2)2(8)+m(9.5 - 8n)²(2)
Om(8)2(2)+m(9.5-8ft)²(2n)
