Here is your answer :
Answer 1 :
Volume of the Cylinder = πr²h
Therefore, The Volume of the Cylinder is 50.27 Feet
By Rounding, 50 Units/Feet
Answer 2 :
So, volume is always cubed since you have l x w x h.
A cubic ft is 12 in x 12 in x 12 in = 1728 in3.
35328.78/1728 = 20.44
20.44 x 7.48 = 152.89
About 153 gallons
