Answer:
V = 20πr²
Step-by-step explanation:
In this question, volume of the cylindrical tank has been defined as,
Volume V of the tank = Product of π, the square of the radius of the tank 'r' and the length of the tank 'h'. 
Therefore, formula to calculate the formula will be,
V = πr²h 
If the length of the cylindrical trailer is, 
h = 20 feet
Then the volume of the trailer will be,
V = πr²(20)
V = 20πr²
