A, divide 2.5 by 5 and you get 0.5, multiply that by 9 and you get 4.5. A is the answer
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.
It increased a total of 4 inches.
Answer:
120 meters
Step-by-step explanation:
16 + 82 = 98
98 + 22 = 120
