Answer:
We can fill the cone 54 times with the grain.
Step-by-step explanation:
Amount of grain = 8138.88 cm³
Dimensions of cone:
Radius = 4 cm
Height = 9 cm
Volume of 1 cone =

Let n be the number of times the cone that can be filled.
Thus, we can write:

Thus, we can fill the cone 54 times with the grain.
3 meters = 300 cm
300 cm + 35 cm = 335cm
Each cm is 10mm
So 335 cm = 3350 mm
Answer:
I do not know, but I do know the formula.
The formula is: 12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.
You need 12 square roots of 1764 ?
<span>Why not find the square root of 1764 first (it's 42) and then take 12 of those ?
Hope this helps!</span>
