(4 1/3 * (-1) * 5) / 12 = -1.80555556
Given that grain is falling from a chute onto the ground, forming a conical pile whose diameter is always three times its height.
So if D is the diameter and h is the height of the conical pile then we can write:
D=3h
We know that diameter = 2r, where r is the radius
2r=3h

Volume of conical pile is given by formula

Given that volume is 1110 cubic feet.
Now plug the values of Volume and r into equation of volume





take cube root of both sides
7.78103342467=h
Hence height is approx 7.78 feet.

Answer:
The percent of time that was spent on reading is 12%
Step-by-step explanation:
To figure this question out, first add up all of the known percentages. So for this question, this would be: 11 + 28 + 22+ 15 + 12, or 88. The total of all the percentages must be equal to 100%. So, subtract the sum of all the known percentages from 100.
100 - 88 = 12%
Hope this helps! ^-^
