Aran moved a cone-shaped pile of sand that had a height of 4 ft and a radius of 3.2 ft. He used all of the sand to fill a cylindrical pit with a radius of 6 ft.
How high did the sand reach in the pit? Use 3.14 to approximate pi and round your answer to one decimal place.
ft
I understand the first part I just need help with the second part. The first is 42.87(V=cone) I need help finding the height of the cylinder.
so first find the volume of the cone 1/3 times height times area of base area of bse=circle=pi times radius^2 pi aprox 3.141592 radius=3.2 3.141592 times 3.2^2=32.1699 1/3 times 4 times 32.1699=42.89
volume=42.89
volume of cylinder filled=area of base times height area of base=circle radius=6 3.141592 times 6^2=113.097 113.097 times h=42.89 divide both sdies by 113.097 height=0.379 ft or aprox 0.4 ft
