Question 322619: An aluminum can has a volume of 250 gallons. What is its volume in cubic feet?
I believe I correctly answered this as 250gallons *.1337ft cubed = 33.425
so the volume is 33.425 ftcubed.
Next I need to use that volume (33.425ft cubed) to express the height(h) in terms of the radius (x)
I believe the formula would be h=v/pix^2 so
h=33.425ft^3/3.14x^2 I am not sure how to solve this or what is meant by express h in terms of x
Thank you so much for your help

Question 324004: Farmer John stores grain in a large silo located at the edge of his farm.. The cylinder-shaped silo has one flat, rectanular face that rests against the side of his barn. The height of the silo is 30 feet and the face resting against the barn is 10 feet wide. If the barn is approximately 5 feet from the center of silo, determine the capacity of Farmer John's silo in cubic feet of grain.
Isn't the capacity the same as volume, so I need to use the formula lxwxh. Does the silo means this is an inscribed square. Do I need to find the area of the rectangle and the area of the square. I really do not understand how I am suppose to set this up.
