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.

Step-by-step explanation:
Given: Chandler walk 1/16 km every 10 minutes.
First, lets find how many 10 minutes in one hours or convert minutes in hours.
∴ Time=
Now, finding kilometres travelled in 1 hour.
Distance travelled=
Distance travelled =
Converting into decimal will have 0.375 km.
∴ will chandler walk in 1 hour.
