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.
N + d = 20 (there are a total of 20 nickels and dimes).05n + .1d = 1.4 (total change equals $1.40)
Answer: C≈62.83ft
Step-by-step explanation:
simply take your radius and times it by 2 and you get 20. then times twenty by pi.
Answer:
<h3>The volume is 144.</h3>
Step-by-step explanation:
Volume of a rectangular solid = l × w × h
where
l is the length
w is the width
h is the height
From the question
l = 12 feet
w = 3 feet
h = 4 feet
Volume = 12 × 3 × 4
= 144 feet
Hope this helps you.
