The radius is half the diameter, so r=15 feet.
Let h = tallness of only the straight cylinder portion. The whole silo tallness will be . Your question is unclear, but you want a final result of either h or h+r.
Volume of the silo, .
feet, just the straight cylinder part.
The whole silo from top to bottom is feet.
