Alarge dump truck will empty its full load of stone onto a small plot of land for storage. the rock forms a cone that is 9 feet tall. the truck holds 144 cubic feet of stone. what is the area of the circular base of the pile of stones

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
